Photochemicalreactions of 2-(pentamethyldisilanyl)furan and 2-(pentamethyldigermanyl)furan have been investigated by chemical trapping experiments and laser flash-photolysis. On irradiation, the furylated catenates of Group 14 elements undergo silicon-silicon σ bond and germanium-germanium σ bond homolysis to give a pair of silyl radicals and germyl radicals, respectively. In CCl4, these radicals

The first example of silylene insertion into a SH bond in solution is described. The trialkoxysilanethiols, significantly more acidic than carbon thiols, were found to be efficient trapping agents for photochemically-generated dimethylsilylene. Chemical evidence for insertion products is presented. A surprisingly high yield of products of insertion of more than one Me2Si unit was observed. In contrast
