Photoinduced reductive coupling of organochlorosilanes with SmI2/Sm

We report efficient reductive dimerization of chlorosilanes with SmI2/Sm in 1,2-dimethoxyethane upon visible light irradiation. This procedure can be applied to the synthesis of polysilanes from dichlorosilanes. The molecular weight of the obtained polysilanes was higher and their molecular weight distribution was narrower than the polysilanes produced by reactions with SmI2/Sm in dark.

Electrolysis of iodosilanes with Al/Pt electrodes in pivalonitrile results in the formation of the Si-Si bonds to give the corresponding disilanes.On the other hand, the electrolysis of various halosilanes such iodo-, chloro-, and fluorosilanes with Pt/Pt electrodes in the presence of phenylacetylene leads to the formation of the Si-sp-carbon bonds to give phenylethynylated products.

Electrochemical Oxidation of Hydrosilanes. A Synthetic Approach to Halosilanes and Disilanes

Electrolytic oxidation of dimethylphenylsilane (1) in the presence of CuCl2 or CuCl afforded chlorodimethylphenylsilane in high yields (>90percent), while similar electrolysis of 1 in the presence of BF4- ions afforded fluorodimethylphenylsilane in 90percent yield. 1,2-Diphenyltetramethyldisilane was obtained from 1 in 48percent yield by the electrolysis with a Pt-Cu electrode system.A "paired" electrolysis of methyldiphenylsilane on the anode and chloromethyldiphenylsilane on the cathode afforded 1,2-dimethyltetraphenyldisilane in 64percent yield.

Copper-Catalyzed Cross-Coupling of Silicon Pronucleophiles with Unactivated Alkyl Electrophiles Coupled with Radical Cyclization

A copper-catalyzed C(sp3)-Si cross-coupling of aliphatic C(sp3)-I electrophiles using a Si-B reagent as the silicon pronucleophile is reported. The reaction involves an alkyl radical intermediate that also engages in 5-exo-trig ring closures onto pendant alkenes prior to the terminating C(sp3)-Si bond formation. Several Ueno-Stork-type precursors cyclized with excellent diastereocontrol in good yields. The base-mediated release of the silicon nucleophile and the copper-catalyzed radical process are analyzed by quantum-chemical calculations, leading to a full mechanistic picture.
