Herein we report on a series of bulky bis(alkyl)‐ and bis(silyl)‐ substituted polysilanes. Moreover, we performed desilylation and dechlorination experiments with them. These compounds were characterized by multinuclear NMR spectroscopy, mass spectrometry, and X‐ray crystallography. It was found that the selective formation of silyl mono‐ and di‐anions is crucial for the successful isolation of these

The electrochemical oxidation of cyclic peralkylsilanes undergo ring opening followed by further Si-Si bond cleavage and reaction with BF4- to form alpha,omega-difluorosilanes, F-(SiR2)n-F, as major products.

Stannylsilanes were synthesized in high yields by reaction of organotinchlorides with organofluorosilanes and magnesium. The fluorosilanes were prepared in good yields and under mild conditions by reaction of the corresponding chlorosilanes with [n-Bu4N][Ph3SnF2]. All products were characterized by Si-29, Sn-119 NMR spectroscopy and elemental analysis.
