in dichloromethane
byproducts: trimethylchlorosilane; reaction with three or more equiv. trimethylmethoxysilane at -78°C. The mixture was allowed to warm to room temp., concg. under reduced pressure, then hexane was added to give a white cryst. solid (all operations in an inert atmosphere); washing with hexane, dried under vac., elem.anal.;
