Abstract

Interaction mechanism of (CH3)3SiX silanes (X=Br, I, N3, NCS, NCO, CN, NCNSi(CH3)3 and SO4Si(CH3)3 with dehydrated silica surface has been studied by IR spectroscopy. It has been established that (CH3)3SiCN, (CH3)3SiBr, (CH3)3SiI and [(CH3)3Si]2SO4 can be used as soft silylating agents for endcapping.

Abstract

Изучен механизм взаимодействия силанов общей формулы (CH3)3SiX (X=Br, I, N3, NCS, NCO, CN, NCNSi(CH3)3, SO4Si(CH3)3) с поверхностью дегидратированного кремнезема методом ИК-спектроскопии. Установлено, что (CH3)3SiCN, (CH3)3SiBr, (CH3)3SiI и [(CH3)3Si]2SO4 могут быть использованы как мягкие силилирующие агенты для эндкеппинга.
