An unprecedented transfer silylation of alcohols catalyzed by the strong Lewis acid B(C6F5)3 is described. Gaseous Me3SiH is released in situ by B(C6F5) 3-catalyzed decomposition of 3-trimethylsilylcyclohexa-1,4-diene and subsequently reacts with an alcohol in a dehydrogenative Si-O coupling promoted by the same boron catalyst. Benzene and dihydrogen are formed during the reaction, but no salt waste is. This expedient protocol is applicable to several silicon groups, and the preparation of trimethylsilyl ethers presented here is potentially useful for alcohol derivatization prior to GLC analysis.

, (2008/06/13)
A process for producing compounds of the formula (CH3)3 SiORLi where in R is selected from alkyl groups containing 2 to 10 carbon atoms and aryl groups containing 6 to 10 carbon atoms by reacting, in an inert atmosphere, in a hydrocarbon solvent, a haloalcohol of the formula HORX wherein R is selected from alkyl groups containing 2 to 10 carbon atoms and aryl groups containing 6 to 10 carbon atoms and X is selected from chlorine or bromine, is reacted with hexamethyldisilazane at a temperature between 20° C. and the reflux temmperature of the solvent after which the resulting product, a trimethylsilyloxyalkylhalide compound, is reacted at a temperature between 50° and 160° C., with powdered lithium metal to produce the (CH3)3 SiORLi compound.
