Synthesis and Structural Characterization of Isomeric Bis [3,4,5,6-tetrakis(trimethylsilyl)cyclohexen-1-yl] dimethoxysilanes

摘要

The syntheses of polysilylated cycles from aromatic precursors have been accomplished by Birch type reductive silyla-tion " and electrochemical silylation. Although the strategy of Birch type reductive silylation has several drawbacks vs electrochemical silylation such as using metal reducing agents, and irregular yields, it has been well developed as one of useful methods for the formation of carbon-silicon bonds in both carbon and organosilicon chemistry. Reductive polysilylations of PhSiCl3 and PhMeSiCl2 were reported to occur with excess lithium and Me3SiCl in THF to yield tetrasilylated cyclohexene (Ttc = tetrakis(trimethylsilyl)cyclohex-1-ene) derivatives.
