Abstract

The invention comprises O-aryl thiophos-phonates having the general formula <FORM:0998604/C2/1> in which n is 1 or 2, R1 is a hydrocarbon group having 1 to 8 carbon atoms which is free from olefinic and acetylenic unsaturation and R is a hydrocarbon group having 1 to 8 carbon atoms or a halogen-substituted C2-C6 aliphatic hydro carbon group which contains only halogen atoms having an atomic number of from 8 to 36 (i.e. Cl, Br or F) and in which the a -carbon atom thereof is free from halogen-substituents. They may be obtained by reacting a thiophosphoryl halide of the formula <FORM:0998604/C2/2> wherein Z is Cl or Br, with a phenol of the for mula <FORM:0998604/C2/3> in the presence of an acid acceptor e.g. sodium or potassium carbonate or a tertiary amine. R1 and R (when hydrocarbon) may be alkyl, aryl, alkaryl, aralkyl or cycloalkyl and R may additionally be an alkenyl or alkynyl group. Preferred reaction temperatures are from 10 DEG to 120 DEG C. and an inert organic solvent may be present, e.g. benzene, toluene, xylene, acetone, butanone or dioxane. Several examples are given and the products have pesticidal proper ties (see Division A5).ALSO:An insecticidal composition comprises an inert solid or liquid carrier and an O-aryl thiophosphonate having the general formula <FORM:0998604/A5-A6/1> wherein n is 1 or 2, R1 is a C1-C8 hydrocarbon group free from olefinic or acetylenic unsaturation and R is a C1-C8 hydrocarbon group or a halogen-substituted C2-C6 aliphatic hydrocarbon group which contains only halogen atoms having an atomic number of from 8 to 36 (i.e. Cl, Br or F) and in which the a -carbon atom thereof is free from halogen substituents (see Division C2). The composition may be in the form of pellets, granules, powder, dust, aerosol, spray concentrate, suspension, or emulsion or in semi-solid form. Other pesticides including nematocides, bactericides and herbicides may also be present. The radical R1 in the formula and the radical R when hydrocarbon may be alkyl, aryl, alkaryl, aralkyl or cycloalkyl and R may additionally be an alkenyl or alkynyl group.
