Abstract
Main products of the reaction of vinyltrichlorosilane VinSiCl3 with DMSO in the medium of tetra-(alkoxy)silane are linear siloxanes (RO)3Si[OSiVin(OR)]OSi(OR)3, RO[Vin(RO)SiO]nSi(OR)3 (R = Me, Et, n = 0–2) and the hitherto unknown cyclic siloxanes [Vin(RO)SiO]m[(RO)2SiO]4–m (m = 1–3) formed in the ratio of 70: 30%. A tentative scheme of their formation is suggested with participation of the products of the alkoxy groups exchange between vinyl(alkoxy)dichloro-, vinyldi(alkoxy)chloro-, trialkoxychloro-, and dialkoxydichlorosilanes.
