synthetischea convenient one-pot procedure has been developed by Kemp and Cowley in which trimethylsilylchloride reacts with dichloromethane in the presence of nBuLi at 110°Cto give bis(trimethylsilyl)dichloromethane.1 This intermediate is sequentially treated with nBuLi and ethanol to yield chlorobis(trimethylsilyl)methane. A number of other syntheses have been described
