A new method was developed to achieve highly selective monochlorination of alpha,omega-dihydridosiloxanes, ((H)Me2SiO-(SiMe2O)(n)-SiMe2(H), n = 0-2; (H)R2Si-O-SiR2(H); R= Me, 'Pr, Ph; 3,5-dihydridooctamethyl tetrasiloxane, Me3SiO-(Si(H)MeO)(2) -SiMe3) with trichloroisocyanuric acid (TCCA). The dependence of the selectivity of the monochlorination on the siloxane chain length is also discussed. (C) 2018 Elsevier B.V. All rights reserved.

The acetolysis reaction of 1-chloro-1,3,5-trimethyl-3,5-bis(trimethylsiloxy)cyclotrisiloxane was investigated using 29Si NMR spectroscopy. The three possible configurational isomers, formed in the synthesis, could not be separated.
使用29 Si NMR光谱研究了1-氯-1,3,5-三甲基-3,5-双(三甲基甲硅烷氧基)环三硅氧烷的乙酰水解反应。合成中形成的三种可能的构型异构体无法分离。
