CHLORINATIVE CLEAVAGE OF PERMETHYLPOLYSILANES INITIATED BY PHOTO-INDUCED ELECTRON TRANSFER

Article abstract of DOI:10.1246/cl.1985.1781

Irradiation od dodecamethylcyclohexasilane (1) in CCl4-CH2Cl2 in the presence of 9,10-dicyanoanthracene (2) afforded 1,6-dichlorododecamethylsilane in 70percent yield.Fluorescence of 2 was quenched by 1 with a diffusion-controlled rate.A mechanism of free-radical chlorination involving (1)⁺ is proposed.
