Abstract
Procedure for the preparation of diurethanes with herbicidal effect, characterized in that a) compounds of the general formula are reacted **(See formula)** with an amine of the general formula **(See formula)** in the presence of an acid acceptor, for example with the addition of excess amine or an inorganic base, such as for example sodium hydroxide, sodium carbonate, potassium carbonate or a tertiary organic base such as for example triethylamine; or b) compounds of the general formula are reacted **(See formula)** in the presence of a tertiary organic base, such as for example triethylamine or pyridine or in the form of alkali metal salts with carbamoyl chlorides of the formula **(See formula)** at temperatures from 0 to 100ºC or -if R1 means hydrogen- with isocyanates of the general formula Rs-N = C = D in the presence of a catalyst, conveniently an organic base; or c) compounds of the general formula are hydrogenated (if R1 and R2 do not mean any easily hydrogenatable radical) **(See formula)** catalytically, for example using nickel in methanol to form the corresponding amine and then reacted with compounds of the general formula C1-COXR3 in the presence of an acid acceptor, for example an inorganic base, such as sodium hydroxide, sodium carbonate or potassium carbonate, or a tertiary organic base, such as for example triethylamine, to form the desired process products, and are isolated these then in the usual way, having R1, R2, R3 and X mean the two above.
