Abstract

The reactions of cis-Cp*W(CO)₂(MeCN)Me (1) with thiophene or 3-methylthiophene resulted in selective α-C-H bond activation to give cis-Cp*W(CO)₂(MeCN)R [R = 2-C₄H₃S (2a), 2-C₄H₂S-4-Me (2b)]. 2a reacted with 3-methylthiophene to afford thienyl exchange products 2b and thiophene in addition to decomposition products. Reversibility of the exchange reaction was shown by the reaction of 2b with thiophene.
