Abstract
The invention comprises phosphonic acid esters of the general formula: <FORM:0963404/C1/1> wherein R and R1 which may be the same or different are phenyl radicals, alkyl radicals containing up to 6 carbon atoms, alkyl phenyl, chlorophenyl, isocyanatophenyl, isocyanatoalkylphenyl or isocyanatobenzyl phenyl radicals, R3 is an alkyl, chloroalkyl or alkenyl radical containing up to 4 carbon atoms or both R3's taken together stand for an unsubstituted or substituted alkylene radical and R2 stands for a cyano, nitroso, chloroformyl (-COCl), thiochloroformyl (-CSCl), trichloromethylmercapto, phosphoric acid ester, alkylcarbonyl, chloroalkyl carbonyl, aryl carbonyl, nitrophenyl carbonyl or alkenyl carbonyl or carboxylic acid ester group or a radical of the general formula: <FORM:0963404/C1/2> in which R, R1 and R3 are as defined above. They may be obtained by reacting an appropriate N,N,N1-trisubstituted haloformamidine with an appropriate triorganophosphite of the general formula: (R3O)3P wherein R3 is as defined above. Reaction is suitably effected at between 20 and 150 DEG C. and solvents or diluents may be present. If the N,N,N1-trisubstituted haloformamidine contains in the R2 radical another easily labile halogen atom suitable for the Arbusow reaction the quantity of organophosphite may be so chosen that both halogen atoms can react with the phosphite e.g. as in the reaction: <FORM:0963404/C1/3> The products have pesticidal properties (see Division A5). Specification 951,779 is referred to.ALSO:A pest control agent contains a solid or liquid diluent or p carrier and a phosphonic acid ester of the general formula <FORM:0963404/A5-A6/1> wherein R and R1 which may be the same or different are phenyl radicals, C1-C6 alkyl radicals, alkylphenyl, chlorophenyl, isocyanatophenyl, isocyanato-alkylphenyl or isocyanatobenzyl phenyl radicals, R3 is an alkyl, chloroalkyl or alkenyl radical containing up to 4 carbon atoms or both R3's taken together stand for an unsubstituted or substituted alkylene radical and R2 is a cyano, nitroso, chloroformyl (-COCl), thiochloroformyl (-CSCl), trichloromethylmercapto, phosphoric acid ester, alkylcarbonyl, chloroalkylcarbonyl, arylcarbonyl, nitrophenylcarbonyl or alkenylcarbonyl, or carboxylic acid ester group or a radical of the general formula <FORM:0963404/A5-A6/2> or <FORM:0963404/A5-A6/3> in which R, R1 and R3 are as defined above. Specification 951,779 is referred to.
