Abstract

The reactions of n-butyllithium and tert-butyllithium with tetramethylstannane have been examined with the objective of determining the degree of competition between proton abstraction from the methyl groups and nucleophilic displacement of these groups from the tin atom. With n-butyllithium the only process observed was displacement of the methyls, all of which were successively displaced by n-butyl groups, but not with high selectivity. With ...
