Abstract

Condensation of triphenylsilane with isopropanol in presence of isopropoxide has been studied in anhydrous medium and the activation parameters have been measured. Dehydration of the medium has been obtained by means of a pre-reaction of triphenylsilane with the residual water in the solvent. In this medium the reaction is extremely slow, moreover, it is inhibited by silanol whose effect would lower the actual catalyst concentration.

Abstract

Изуч⪟на реакция конденсации трифенилсилана с изопропанолом в присутствии окиси изопропила в безводной среде и измерены активационные параметры. Обезвоживание среды осуществлялось в результате предварительной реакции трифенилсилана с остаточной водой растворителя. В такой среде реакция идет очень медленно и к тому же ингибируется силанолом, под действием которого понижлется истинная концентрация катализатора.
