PHOTOCHEMISTRY OF DIBENZO-1,1,2,2,3,3-HEXAMETHYL-1,2,3-TRISILACYCLOHEPTA-4,6-DIENE AND THE GERMANIUM ANALOG. GENERATION OF TETRAMETHYLDISILENE BY FREE-RADICAL DISPROPORTIONATION AND THE FIRST SPECTROSCOPIC DETECTION OF DIMETHYLGERMYLENE

Photolysis of the title compound afforded silafluorene and dibenzo-1,2-disilacyclohexadiene as primary photoproducts.Two reactive intermediates, tetramethyldisilene and dimethylsilylene, were trapping.The dimethylgermylene, derived from germanium analog, was first observed by electronic spectra.
