INTRODUCTION
The role of silyl groups has been recognized of late as an important
part of organic chemistry from both analytical and synthetic points
of view; especially as a protecting group in many syntheses of reasonable
complexity.1 Generally the formation of silyl ethers is carried
out by treatment of alcohols with silyl chlorides or silyl triflates in
the presence of a base;2 Li2S;3 and sometimes a nonionic super base
catalyst.4 However; some of these methods frequently suffer from drawbacks
such as lack of reactivity or the difficulty in removal of amine
salts derived from the reaction of by-product acid and cobases during
the silylation reaction. 1;1;1;3;3;3-Hexamethyldisilazane(HMDS) is a
