Abstract
A method for preparing phenyl-containing organosilicon intermediates using an aromatic halogenated solvent during the coupling reaction involving a phenyl Grignard reagent and a precursor silane. The process comprises contacting a phenyl halide with magnesium in a solvent such as ether, or an aromatic halogenated/ether solvent mixture to form a Grignard reagent, and contacting the Grignard reagent with a precursor chlorosilane in aromatic halogenated solvent to form the desired organosilicon intermediates, and then filtering and distilling to acquire the organosilicon intermediate reaction product.
