Abstract

Abstract The present invention relates to novel cyclic phosphoric acid amide esters, a process for producing the same and an insecticide containing the same as active ingredient. The present invention provides novel 4-substituted-1,3,2-oxazaphospholidine derivatives of the general formula: <IMAGE> I wherein R1 represents an alkyl, alkenyl, alkynyl, aralkyl, aralkenyl or aralkynyl group and R2 represents an alkyl group. The compounds of the formula I may be produced by the reaction of a compound of the formula: <IMAGE> II wherein R1 is as hereinbefore defined or an alcoholate thereof with a compound of the formula: <IMAGE> III wherein R2 is as hereinbefore defined and X1 and X2, which may be same or different, each represents an atom or group removable as an anion. The compounds of the formula I have interesting insecticidal activity particularly against houseflies, adzuki-been weevil, mulberry mealy bug etc.
