Photoreactions of (2-substituted-phenyl)pentamethyldisilanes

Abstract--The photochemical formation of silicon-carbon double~bonded intermediates from phenyl, tolyl, naphthyl, 1-alkenyl and phenylethynyl substituted disilanes and their reactions are described. The siliconcarbon double-bonded intermediates generated from phenyl, tolyl and 2-naphthyldisilanes reacted with many organic substances to give 1:1 adducts; the mode of their addition reaction is very different from that of a hitherto reported dimethylsilaethene type of silicon-carbon doublebonded intermediates. Photolysis of 1-naphthyldisilane derivatives in the presence or absence of trapping agents led only to an isomer, 1-hydrosilyl-2-silylnaphthalene. The chemical nature of intermediates from vinyl-and a-styryldisilanes was rather similar to that of the thermally generated dimethylsilaethene-type intermediates. Photolysis of (pentamethyldisilanyl)phenylacetylene gave 1-silacyclopropene and 1-sila-1,2-propadiene which could be trapped by acetone or an alcohol.
