PERFLUOROALKYL DERIVATIVES OF TIN: II. DIMETHYLTRIFLUOROMETHYLTIN CHLORIDE

Abstract

A methyl group is cleaved by chlorine in preference to trifluoromethyl from trimethyltrifluoromethyltin and dimethyltrifluoromethyltin chloride; the significance of this is discussed in terms of the electronegativity of the trifluoromethyl group. The influence of trifluoromethyl on the acceptor properties of the tin atom in dimethyltrifluoromethyltin chloride has been illustrated by means of conductivity measurements. Nuclear magnetic resonance measurements of trimethyltrifluoromethyltin and dimethyltrifluoromethyltin chloride are also reported.
