The 2-methylbut-2-enyl(diphenyl)silyl group: A silyl group easily converted to hydroxyl in the presence of a 1,2-disubstituted C=C double bond

Fleming, Ian,Winter, Stephen B. D.

, p. 7287 - 7290 (1993)

The 2-methylbut-2-enyl(diphenyl)silyl group can be introduced into a variety of organic structures by way of the cuprate reagent 4, and it can then be converted into a hydroxyl group, even in the presence of a C=C double bond, unlike the dimethyl(phenyl)silyl group.
