The photolysis of pentamethyl-2-thienyldisilane (1) in the presence of cyclohe-xane/ethanol gave dimethyl-2-thienylsilane (2), trimethyl-2-thienylsilane (3), trimethyl-ethoxy siland (4) and dimethylethoxysilane (5) as the main products. if ethyl alcoho-d (C2H5OD) was used as a trapping agent, dimethyl-2-thienyldeutrosiland (2d) and dimethyl-etyoxydeutrosiland (5d) instead of 2 and 5 were obtained mechanism was disscused.
