Abstract
Alkoxysilanes are prepared by a process which uses microwave or RF energy. Thus, silicon metal and a copper catalyst are exposed to microwave radiation in the presence of an appropriate hydroxy compound, such as, an alcohol, and a catalyst, to yield the corresponding trialkoxysilane. The desired alkoxysilanes are prepared with high selectivity and at lower temperatures and shorter times than traditional approaches allow.
