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: ##STR1## wherein R.sub.1 represents an alkyl, alkenyl, alkynyl, aralkyl, aralkenyl or aralkynyl group and R.sub.2 represents an alkyl group. The compounds of the formula I may be produced by the reaction of a compound of the formula: ##STR2## wherein R.sub.1 is as hereinbefore defined or an alcoholate thereof with a compound of the formula: ##STR3## wherein R.sub.2 is as hereinbefore defined and X.sub.1 and X.sub.2, 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.
