  Utility of trichloroisocyanuric acid in the efficient chlorination of silicon hydrides

  摘要：

  The potential of trichloroisocyanuric acid (TCCA) as a chlorination agent for efficient conversion of Si-H functional silanes and siloxanes to the corresponding Si-Cl functional moieties was explored. In comparison to methods using other chlorinating agents, TCCA is inexpensive, results in a much faster reaction and produces a high purity product with a conversion that is essentially quantitative. A variety of chloro derivatives of linear and cyclic structures have been synthesized from silicon hydrides using this reagent with impressive yields that typically exceed 90%: PhSiCl3 (97.5%); PhMeSiCl2 (95.5%); Ph3SiCl (97.5%); Vi(3)SiCl (98.7%); (EtO)(3)SiCl (99.7%); t-Bu3SiCl (similar to 100%); (MeClSiO)(4) (86.5%); (MeClSiO)(5) (95%); (MeClSiO)(7) (96.5%); Ph(OEt)(2)SiCl (98%); ClMe2SiOSiMe2Cl (98.6%); ClMe2SiOSiMeClOSiMe2Cl (94.6%); ClMe2Si(OSiMeCl)(2)OSiMe2C l (92.3%); (Me3SiO)(3)SiCl (97%); Me3SiOSiClPhOSiMe3 (99%); Me3SiO(SiMeClO)(3)SiMe3 (95.7%); ClSi(OSiMe3)(2)OSi(OSiMe3) Cl-2 (93.6%).For monohydridosilanes, dichloromethane (CH2Cl2) was a suitable solvent in which nearly quantitative conversion was observed within several minutes following the addition of the silanes to TCCA. For certain cyclic and linear siloxanes, and especially silanes containing multiple hydrogen atoms on the same silicon for which the reaction is sluggish in CH2Cl2, tetrahydrofuran (THF) was the preferred solvent. For a sterically demanding silane that did not undergo chlorination even in THF viz., HSi(OSiMe3)(2)O-Si(OSiMe3)(2)H, 1,2-dichloroethane was the best solvent. (c) 2007 Elsevier B.V.
