Chemical Properties
Clear colorless liquid
Uses
Selective silylation of primary hydroxy groups in the presence of secondary alcohol.
Uses
The bulky isopropyl groups (vs. ethyl) allow for more selective reductions, e.g., beta-selective reduction of anomeric C-phenyl ketals, but do not diminish their activity (e.g. in the copper triflate catalyzed reductive etherification of trimethylsilyl ethers).
Uses
Triisopropylsilane is used as a protecting group in peptide synthesis and is also used as a reducing agent for the selective reduction of anomeric C-phenyl ketals. It is used in the selective silylation of primary hydroxyl groups without affecting the secondary hydroxyl group. It is used in the preparation of anti-1,2-diols catalyzed by a Ni(O) N-heterocyclic carbine complex with high diastereoselectivity.
Application
Very sterically-hindered silane. Used as a cation
scavenger in the deprotection of peptides.
