Cross-linked poly(4-vinylpyridine/styrene) copolymer-supported bismuth(III) triflate: An efficient heterogeneous catalyst for silylation of alcohols and phenols with HMDS

experimental part, p. 608 - 615 (2011/11/12)
Cross-linked poly(4-vinylpyridine/styrene) copolymer-supported bismuth(III) triflate (30P/S-Bi) effectively activates hexamethyldisilazane (HMDS) for the silylation of alcohols and phenols. By the use of this heterogeneous catalytic system, a wide range of alcohols as well as phenols are converted into their corresponding trimethylsilyl ethers in high yield under mild reaction conditions. The catalyst was reused more than 10 times without significant loss of its catalytic activity.
Mild and efficient silylation of alcohols and phenols with HMDS using Bi(OTf)3 under solvent-free condition

A very efficient and mild silylation of alcohols and phenols with hexamethyldisilazane (HMDS) at rt is developed using Bi(OTf)3 as the catalyst. Primary, secondary and tertiary alcohols as well as phenols are excellently converted into correspo
A Novel Mechanism for the Conversion of α-Cyclopropylbenzyl Alcohol into γ-Trimethylsilylbutyrophenone

Mechanistic studies of the reaction between α-cyclopropylbenzyl alcohol and methyl-lithium followed by hexamethyldisilane indicate that disproportionation of intermediate (4) with trimethylsilyl anion as catalyst provides cyclopropyl phenyl ketone; in situ 1,4-addition of trimethylsilyl anion to the latter compound leads to the major product, γ-trimethylsilylbutyrophenone (2).
