A stable aquo-complex of lithiated di-tert-butylfluorosilanol. Synthesis and crystal structure

Abstract

It was possible by crystallizing the lithiated derivative of di-tert-butylfluorosilanol to isolate a stable aquo-complex of this tetrameric compound as the first hydrolysis product. An X-ray diffraction study has revealed the existence of ([R2Si(F)OLi]3·[R2Si(OH)OLi] ·THF·H2O (R = CMe3; THF = tetrahydrofuran). The mechanism of hydrolysis from [R2Si(F)OLi]4 to this aquo-complex is discussed.
