Selective dehydrogenative coupling of di- and trihydrosilanes with alcohols catalyzed by PdCl2 or NiCl2 afforded alkoxyhydro- and dialkoxyhydrosilanes in good yield. Further treatment of the resulting alkoxyhydrosilanes with carbon tetrachloride or allyl bromide in the presence of the same catalyst led to the formation of alkoxychloro- and alkoxybromosilanes, respectively. Similar reactions of dialkoxyhydrosilanes with carbon tetrachloride afforded dialkoxychlorosilanes in good yield, although contamination of small amounts of trialkoxysilanes and alkoxydichlorosilanes was detected in the products. Selective substitution of the alkoxyhalosilanes with nucleophiles is also reported.

The preparation and evaluation of a new class of alcohol-protecting groups, the alkoxydiphenylsilyl ethers, are described.In particular, tert-butoxydiphenylsilyl ethers, which can be formed from primary, secondary, or tertiary alcohols and tert-butoxydiphenylsilyl chloride, offer the useful synthetic properties of acid stability and high fluoride reactivity.Opportunities for selective silyl group cleavage are highlighted.
