On the Properties of Some α-Hydroxy Phosphonates and Related Compounds

Abstract

In search for effective organophosphorus esters against the larva of the cotton leaf worm (Prodenia litura F), some α-hydroxy phosphonic acid dimethyl esters and related compounds have been synthesized. The effect of substitution on the antiesterase activity and toxicity towards Prodenia larvae has been investigated. The infra-red spectra of the prepared phosphorus esters are discussed.
