The combination of InCl3 and Me3SiBr provided an enhanced Lewis acid system that can be used to promote a wide range of direct coupling reactions between alcohols and silyl nucleophiles in non-halogenated solvents, such as hexane or MeCN. The enhanced

The cleavage of a peptide resin attached to a phenylacetomidomethyl (PAM) resin was investigated using bromotrimethylsilane (TMSBr) with thioanisole in trifluoroacetic acid (TFA), and by chlorotrimethylsilane (TMSCl) in the same reagents with lithium bromide. Both TMSBr and TMSCl cleaved the
