Boron Compounds; 69. Introduction and Removal of t-Butyldimethylsilyl Groups via Diethylboryloxy Compounds
Dahlhoff, Wilhelm V.,Taba, Kalulu M.
, p. 561 - 562 (1986)
O-Diethylboryl compounds react with t-butyldimethylsilylacetylacetonate in the presence of trimethylsilyl triflate at room temperature to give the corresponding t-butyldimethylsilyl ethers, which are easily deprotected, forming O-diethylboryl ethers on re
Preparation of nano silica supported sodium hydrogen sulfate: As an efficient catalyst for the trimethyl, triethyl and t-butyldimethyl silylations of aliphatic and aromatic alcohols in solution and under solvent-free conditions

Nano silica supported sodium hydrogen sulfate has been prepared by mixing NaHSO4 with activated Nano silicagel. We wish to report a new method for the synthesis of trimethyl (TMS), triethyl (TES) and t-butyldimethyl silyl (TBS) ethers from benzylic, allylic, propargylic alcohols, phenols, naphtholes and some of phenolic drugs in the solution and under solvent-free conditions.
Highly diastereoselective iron-mediated C(sp2)-C(sp3) cross-coupling reactions between aryl grignard reagents and cyclic iodohydrine derivatives

trans-2-Arylcycloalcohol derivatives are obtained in high diastereoselectivity by the iron-mediated cross-coupling of cyclic TBS-protected iodohydrines with aryl Grignard reagents (see scheme; TBS=tert- butyldimethylsilyl). The stereoconvergent cross-coupling of a chiral TBS-protected 2-iodocyclohexanol provides the 2-arylcyclohexanols with no loss of stereochemical purity, and is a valuable alternative to the enantioselective opening of symmetrical epoxides.
