Abstract
The invention comprises compounds of the general formula <FORM:0899243/IV (b)/1> wherein R1 and R2 are chlorine or hydrogen atoms and R3 is a hydrocarbon radical, substituted or unsubstituted and a process for the preparation thereof, wherein a substituted benzyl compound of the formula <FORM:0899243/IV (b)/2> is reacted with a carboxy compound of the formula R3-COY, wherein R1 and R2 are chlorine or hydrogen atoms, R3 is a hydrocarbon radical, substituted or unsubstituted, X is halogen or a hydroxy radical and Y is hydroxyl or halogen or the group -OM where M is an alkali metal radical, provided that X and Y are not both halogen. The esters of the invention are employed in herbicidal compositions (see Group VI). The radical R3 may be selected from unsubstituted alkyl, aryl, aralkyl or aroxyalkyl radicals or similar groups substituted with hydroxy, carboxy, halogen, alkyl or nitro groups. The preparation of 2 : 3 : 6-trichlorobenzyl acetate, - 21 - methyl - 41 - chlorophenoxy acetate, -a ,a -dichloropropionate, -lactate, -paranitro - benzoate, - trichloroacetate, 2, 6 - dichlor - benzyl acetate and 2 : 3 : 5 : 6-tetrachlorobenzyl acetate is described in examples.ALSO:Herbicidal compositions comprise as active ingredient a substituted benzyl ester of the general formula <FORM:0899243/VI/1> wherein R1 and R2 are chlorine or hydrogen atoms and R3 is a hydrocarbon radical, substituted or unsubstituted (see Group IV (b)). The radical R3 may be selected from unsubstituted alkyl, aryl, aralkyl, or aroxyalkyl radicals or similar groups substituted with hydroxy, carboxy, halogen, alkyl or nitro groups. The active substances may be employed in admixture with clays, sands, talc, mica and fertilizers or with water or organic solvents. Solutions in organic solvents may be dispersed in water with or without the use of wetting agents. Representative of the wetting agents specified are aliphatic or aromatic sulphates and sulphonates and quaternary ammonium compounds. Specific compositions described include aqueous dispersions of methoxyethanol solutions of 2 : 3 : 6-trichlorobenzyl acetate and of 2 : 3 : 6-trichlorobenzyl-21-methyl - 41 - chlorophenoxyacetate and china clay in admixture with 2 : 3 : 6-trichlorobenzyllactate, -a ,a -dichloropropionate, -21-methyl-41-chlorophenoxyacetate and -acetate.
