Basenko, M. Voronkov, I. Gebel] Alkyltrichlorosilanes react with DMSO (molar ratio 1 : 1 0 °C) to give cyclic oligoalkylchlorosiloxanes of the general formula [R(Cl)SiO] n (where R=Me or Et;n=3-6). With an excess of alkyltrichlorosilane (2: 1), linear oligoalkylchlorosiloxanes Cl[R(Cl)SiO] m SiCl2R (where R=Me or Et;m=1-5) are also formed. In the presence of hexamethyldisiloxane (molar ratio Cl3SiR : DMSO: (Me3Si)2O=1:1:2, 20 °C), the reaction products are both cyclic and linear oligoalkyl(trimethylsilyloxy)siloxanes [R(Me3SiO)SiO] n (n=3-5) and Me3Si[OSi(OSiMe3)R] m OSiMe3 (m=1-3), respectively. The reaction of DMSO with trichloro(vinyl)silane and hexamethyldisiloxane occurs in a similar manner. A plausible scheme of formation of the final products via intermediate alkylchlorosilanones RClSi=O and alkyl(trimethylsilyloxy)silanones is discussed.
