Dissymmetric tertiary-alkyl tin(IV) compounds
Abstract
The preparation of some new dissymmetric alkyl compounds of tin(IV) is described, in particular those containing t-butyl and t-pentyl groups. The 1H n.m.r. spectra of these compounds at 100 and 220 MHz has been investigated, and the appearance of magnetic non-equivalence is discussed. A temperature-dependence study of the 1H n.m.r. spectra confirms that the tetra-alkyltin(IV) compounds are stereochemically stable.
