Photolysis of 1,1,2,2-tetramethyl-1,2-bis-(2'-thienyl)disilane (I) in methanol/benzene leads to dimethyl-bis-(2'-thienyl)silane (III), 2-methoxydimethylsilylthiophene (IV) and 2-dimethylsilylthiophene (V) as a major products.The mechanism of this reaction, has been explored by use of methanol-d4.The predominant pathway leading to IV and V appears to involve direct reaction of methanol with the photoexcited state of I.
