摘要：

Coordination of Mn(CO)(3)(+) to the carbocyclic ring of benzothiophenes activates the C(aryl)-S bond to reductive cleavage, affording metallathiacycle 5. When the 7-R substituent in 5 is methyl or ethyl (but not hydrogen), rapid C(vinyl)-S bond scission ensues to give isomer 6, which subsequently undergoes a metallathiacycle ring contraction to yield complex 7.

[2] Like on heterogeneous hydrodesulfurization (HDS) catalysts, the homogeneous HDS of benzo[b]thiophene is achieved by the concomitant action of a metal promoter (Rh) and an active HDS component (W) [J].
