Selective silylation of primary OH groups in the presence of secondary has been carried out with this reagent in combination with CsF and imidazole: J. Organomet. Chem., 282, 155 (1985).
Triethylsilane and triisopropylsilane have been studied as cation scavengers in the deprotection of peptides with TFA, and were found to give good results, with triisopropylsilane being particularly effective in trapping trityl cations in the TFA deprotection of cysteine containing peptides. The use of triisopropylsilane minimizes the risk of reduction of the indole nucleus in tryptophan-containing peptides: Tetrahedron Lett., 30, 2739 (1989).
