Description
AGRIPAT. S.A.
The present invention concerns new O-methyl 0-(2,2,2,-trihaloethyl) -(2' ,2' -dihalovinyl) phosphoric acid esters, process for the production thereof as well as pesticidal compositions containing these phosphoric acid esters as active ingredients and method for the con rol of pests using the new active substances or compositions containing them.
The new O-methyl 0- (2 , 2 , 2- rihaloethyl) 0- (2 ', 2 ' -dihalovinyl) phosphoric acid esters correspond to the Formula I: 11 OCH^ .
CX.QUO — P ^1) . ^ 0CH= CY2 In this formula: X represents, fluorine or chlorine ,. and Y represents chlorine or bromine.
The new phosphoric acid esters of Formula I are produced according to the invention by converting trimethyl phosphite or 0 ,0-dimethyl phosphorous acid chloride in the presence of a base with a trihaloethano'l of the Formula II CX3CH2OH (II) into an 0 , 0-dimethyl 0- ( 2 , 2 , 2- trihaloethyl) phosphite and reacting this with chloral or bromal.
According to a modification of the process according to the invention, the phosphoric acid esters of Formula I are produced by reacting rime hy1 phosphite and phosphorus trichloride in the presence of an acid-binding agent with a trihaloethanol of the Formula II and chloral or bromal.
For the process according to the ivrvention, the following bases, for example, can be employed: tertiary amines such as trialkylamin.es, pyridine and pyridine bases, inorganic bases such as hydroxides, carbonates and cyanides of alkali metals. Moreover, alkali metal alkanolates can also be employed; such an alkanolate is also formed during the reaction after the addition of metallic alkali metal to the reaction mixture. Tertiary amines, in particular, as well as the inorganic bases listed may be employed to take up the hydrogen halide formed during the reaction of trimethyl phosphite and phosphorus trichloride with trihaloethanol.
The reactions according to the invention' may be performed in the presence or absence of a solvent or diluent. It is advisable to perform the reaction of trimethyl phosphite and phosphorus trichloride with trihaloethanol in the presence of a solvent which is inert towards the reaction componei^ts ; for this purpose aromatic hydrocarbons such as benzene, toluene, xylenes, and halogenated hydrocarbons such as chloroform, carbontetrachloride and" chlorobenzene have proved suitable. For the process according to the invention, it has been found expedient to employ the trimethyl phosphite in excess, the other reaction components, however, in molar equivalents. If 0,0-dimethyl phosphorous acid chloride is used in place of trimethyl phosphite, the reaction components are employed in equimolar amounts. Whereas by the interchange of ester radicals-- rimethyl; phosphite/ trihaloethanol-- the base can be employed in catalytic amounts; when the chloride is employed, equimolar amounts of the base are necessary. The reaction temperatures for interchange of ester radicals are in the range of 60-150°C, for the reaction of acid chloride/ trihaloethanol in the range of 0 - 50°, preferably 0 - 30°C. The methaitol which forms in the reaction is continuously removed by distillation from the reaction mixture, the hydrochloride base is removed by filtration. The intermediate product, 0,0- dimethyl 0- (2 , 2 , 2- trihaloethy1) phosphite, is then separated by distillation and purified. The reaction of this phosphite with chloral or bromal is performed at temperatures between 20 and 100°C, preferably at 50 to 80°C.
Depending on the reactivity of the individual reaction components, heating or cooling of the reaction mixture is required.
The modification of the process according to the invention is a "one-container" process. The 0,0-dimethyl 0- (trihaloethy1) phosphite resulting as intermediate can be reacted directly without further purification with chloral or bromal. The phosphoric acid esters of Formula I are then separated from the reaction mixture by distillation; they are obtained in high purity and very good yields. Trimethyl phosphite and phosphorus trichloride are employed in the reaction in a ratio of chloride to phosphite of 1:2 to 1:3, preferably 1:2; trihaloethanol, chloral or bromal and acid-binding agent (base) are employed in equimolar amounts relative to the phosphorus compounds; this corresponds to 3 - 4 mol of the individual reactants , preferably 3 mol. The reaction temperatures for. the reaction of phosphite and trihaloethanol are in the range of 0-50°, preferably 0-30°C; for the reaction of the inter- mediate with chloral or bromal they are from 20-100°, preferably 50-80°C.
From the literature a number of asymmetric 0,0-dialkyl 0- (2 , 2-dichlorovin.yl) phosphoric acid esters are known (cf. for example U . S . patents N os . 2,956,073 and 3,116,201; German patent No. 1,251,745). In general, they are produced by reaction of asymmetric trialkyl phosphorous acid esters (trialkyl phosphites) with chloral according to W. Perkow [cf. Naturwissenschaften 3.9, 353 ff (1952)]. 0-Alkyl 0- (2-chloroethyl) 0- (21 , 2 ' -dichlorovinyl) phosphoric acid esters are obtained according to British patent No. 806,638 from cyclic phosphorous acid esters with chloral. In German patent No. 1,178,420, the production of 0- (2 , 2-dichlorovinyl) phosphoric acid esters with one or two identical or differing halogenated tertiary alkyl radicals from corresponding 0- ( ter -haloalkyl) 0-alkyl phosphorous acid esters and chloral is described. The phosphorous acid esters are obtained in turn from PCl^ a d appropriate alcohols. Since on the one hand the chlorine atoms of the PCl^ cannot be exchanged in exact steps, and on the other hand a separation and isolation of asymmetric ti-ialkyl phosphites having lower alkyl radicals is very difficult, this method of producing the 0,0-di— methyl 0- ( 2 , 2 , 2- trihaloethy1) phosphite could not be used.
The replacement of a trichloroethyI group by the dichlorovinyl radical in tris- (2 , 2-dichloroethyl) phosphorous acid ester v/ith chloral led to 0 ,0-bis- (2 , 2 , 2- trichloroethyl)-l-hydroxy-2,2,2 trichloroethyl phosphonic acid [cf. B.A.Arbuzov, Dokl.Akad.
Nauk USSR 160, 99 ff (1965)].
. By the. process according to the invention, the not-previously-described 0,0-dimethyl 0- (2 , 2 , 2- trihaloethyj.) phosphorous acid esters necessary for the production of the new phosphoric acid ester of Formula I are obtained without difficulty. . They are isolated by distillation from the reaction mixture. In the modification of the process according to the invention, isolation is not necessary; chloral or bro al can be added directly to the reaction mixture after the separation of the precipitated salt.
The new 0-methyl 0- (2 , 2 , 2- trihaloethy1) 0- ( 2 2 ' -dichlorovinyl) phosphoric acid esters of Formula I have excellent insecticidal and acaricidal properties. Compared with known 0-alkyl 0- (21 , 2 ' -dichlorovinyl) phosphoric acid esters, for example the widely used 0 ,0-dimethyl-0-(2 ' ^'-dichlorovinyl pho phate (DDVP) , 0-methyl 0- ( 1-methyl- 1~ trichloro-methyl- ethyl) 0- (2 ', 2 ' -dichlorovinyl) phosphate and 0-methyl 0-(2-chloroethyl) 0- (2 2 ' -dichlorovinyl) phosphate (loc. cit) , the new active substances have a substantially more favorable toxicity for warm-blooded animals and a long-lasting insecticidal effect. They are thus suited, in particular for the protection of stored goods and for the control of insects in buildings, stables, etc.
In the following comparison table the toxicity for warmblooded animals is given.

Schrader, "Die Entwicklung neuer , insektizider Phosphorsaureester , page 40-50, Tests with compounds of the Formula I on insects and arachnids showed that these active substances are good to very good stomach and coiitact poisons and also have a systemic insecticidal dffect..
It has thus been found that the active substances of the Formula I have, in. particular , an excellent, long-lasting effect against insects of the families Muscidae, Stomoxidae and Culicidae, e.g. against the polyvalent-resistant and normally sensitive house lies ( usca domestica) , stable flies (Stomoxys calcitrans) and mosquitoes (e.g. Aedes Aegypti, Culex fatigans , Anophenles Stephens!); against insects of the families Curculinidae , Bruchididae, Dermes- tidae, Tenebrionidae and Chrysomelidae , e.-g. granary weevil's' (Sitophilus granarius) , bean beetles (Bruchidus obtectus) , ' larder beetles (Der estes vulpinus) , mealworms (Teiebrio olitor) , Colorado potato beetles (Leptinotarsa . decemlineata) and their larval stages; against insects of the family Pyralididae, e.g. Mediterranean flour moths (Ephestia klihniella) ; of the family Blattidae, e.g. cock-roaches (Phyllodromia germanica , . Periplaneta americana, Blatta orientalis) ; of the family Aphididae, e.g. bean aphicls (Aphis fabae) ; of the family Pseudococcidae , e.g. citrus mealybugs (Planococcus citri) and of the family Locustidae, e.g. migratory locusts (Locusta inigratoria).
Tests on the said bean aphids and migratory locusts showed an excellent systemic effect.
In addition, the active substances of the Formula I according to the invention have a good action on the larval Ixodidae, Arachnidae and Argasidae. Ψ . In admixture with synergists and auxiliaries having a similar action such as dibutyl succinate, piperonyl butoxide, olive oil, and peanut oil, etc., the range of action of the said active substances can be broadened and in particular the insecticidal -and acaricidal action can be improved.
Likewise, the insecticidal action can be substantially broadened and adjusted to the prevailing conditions by the addition of other insecticides such as, for example, phosphoric, phosphonic , thio- and dithiophosphoric acid esters and amides , halogeiiated hydrocarbons and analogs of DDT-active substance as well as pyrethrines and synergists thereof, acaricidally active substances such as halogeno-benzilic acid. esters such as 4 ' , 41 -dichlorobenzilic acid esters and 41 ,41 -dibromobenzilic acid esters ,, insecticidal and acaricidal carbamates, for example oxime carbamates, aryl carbamates and carbamates of heterocyclic compounds which are enolizable.
Comparison Tests: The insecticidal activity of the new asymmetric phosphoric esters is illustrated by the following tests, using as comparison compound the 0 -methyl 0-- [ 1' , 1' -dimethyl-2 ' , 2 ' , 2 ' trichloroethyl] .-0-[2 , 2 -dichlorovinyl ] phosphate, disclosed in the German patent specification No. 1 178 420. 1.
