Abstract

The reaction of diarylalkylsilanes and-germanes with trityl cation in the presence of a weakly coordinating anion to give the corresponding triarylsilylium or-germylium ions was investigated. This reaction provides a facile access to a larger range of these sterically highly hindered Lewis acids. The factors that promote the substituent exchange were studied, and significant effects of the substituent, of the solvent, and of the group 14 ...
