COMPOSITIONS AND METHODS FOR CONTROLLING ACARIDS AND INSECTS WITH TRIMETHYLTIN DERIVATIVES AND SOME NOVEL TRIMETHYLTIN DERIVATIVES

摘要

The active ingredient of the composition corresponds to the formula: IMAGE in which n = 1 to 10, R' = H, OH, alkoxy or alkyl and X represents various organic radicals; it is especially trimethyl-3-phenylthiopropylstannane or 2-(hydrazinocarbonyl)ethyltrimethylstannane. These compounds can be prepared by reaction of the H2C=CR- group of an olefin with trimethyltin hydride under irradiation by a mercury vapour lamp.
