Abstract

The work described in this thesis consists of an investigation into the use of [Pddppe(MeOH)<sub>2</sub>] [CIO<sub>4</sub>]<sub>2</sub>, AgCIO<sub>4</sub>, (C<sub>6</sub>H<sub>5</sub>)<sub>3</sub>C<sup>+</sup>CIO<sub>4</sub> and (CH<Sub>3</sub>)<sub>3<sub>Si0CIO<sub>3</sub> as catalyst precursors for the reaction of alcohols, particularly methanol, with triphenylsilane. Although the species (C6H5)3SiCIO<sub>4</sub> could not be obtained in a pure form, evidence suggests it plays an important role in the reaction sequences of these precursors leading to the <i>in situ</i> formation of anhydrous perchloric acid. This acid then acts to catalyse the alcoholysis reaction.
