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.

and allylic displacement reactions with 1-vinylcyclohexyl acetate 20 and (Z)-1-cyclopentyloct-2-en-1-yl acetate 22. The silyl group in each of the products was converted into a hydroxy, with the removal of the 2-methylbut-2-enyl group taking place under much milder acidic conditions than those needed to remove the phenyl group from the dimethyl(phenyl)silyl group, and making this group suitable for
