Metal ion-promoted degradation of thiophenes is central to industrial processes aimed at the hydrogenolytic removal of organosulfur impurities from fossil fuels. The C-S cleavage step is specially crucial; three general types of ring-opened thiophene complexes have been identified. In this report we describe a fourth bonding mode for ring-opened thiophene that extends this series and is suggestive of a pathway for extrusion of the S atom. The reduced thiophene complexes were found to readily protonate at carbon. 19 refs., 1 fig.
