Studies on Saligenin Cyclic Phosphorus Esters with Insecticidal Activity Part IX

Derivatives of Phosphonic and Phosphonothionic Acids

Abstract

A number of saligenin cyclic phosphonates and phosphonothionates were prepared and their insecticidal activity and stability were examined. They were less stable than corresponding phosphate esters. 2-Ethyl-4H-l, 3, 2-benzodioxaphosphorin-2-sulfide was the most effective against house flies.
