摘要：

The reaction of tetramesityldisilene (1) with thiobenzophenone (2) gave the first disilathietane, 4,4-diphenyl-1, 1,2,2-tetramesityl-1,2,3-disilathietane (3), as air-stable colorless crystals. An X-ray crystallographic study showed that 3 contains a long silicon-silicon bond (2.443 angstrom) and a highly distorted four-membered ring. Photolysis of 3 in the presence of ethanol afforded two compounds, dimesityl(diphenylmethyl)ethoxysilane (5) and dimesitylethoxysilanethiol (6); in the absence of ethanol photolysis gave the silene 1,1-dimesityl-2,2-diphenylsilene (7), in moderate yield.
