New Approach to the Synthesis of Symmetrical 1,3-Dichloro-1,1,3,3-Tetraorganyl- and 1,1,3,3-Tetrachloro-1,3-Diorganyldisiloxanes

摘要

A series of derivatives of symmetrical 1,3-dichloro-1,1,3,3-tetraorganyl- and 1,1,3,3-tetrachloro-1,3-diorganyldisiloxanes ClRR'Si-O-SiRR' (R = Cl, H, CH (3); R' = CH (3), Et, ClCH (2), Vin, Ph) have been synthesized by a novel efficient reaction of corresponding diorganyldichlorosilane and organyltrichlorosilane RSiCl (3) (3-5-fold excess) with dimethyl sulfoxide in 53 to 91 % yield.
