The electronically unsaturated dirhenium complex [Re 2 (CO) 8 (µ‐AuPPh 3 )(µ‐Ph)] ( 1 ) was obtained from the reaction of [Re 2 (CO) 8 {µ‐η 2 ‐C(H)C(H) n Bu}(µ‐H)] with [Au(PPh 3 )Ph]. The bridging {AuPPh 3 } group was replaced by a bridging hydrido ligand to yield the unsaturated dirhenium complex [Re 2 (CO) 8 (µ‐H)(µ‐Ph)] ( 2 ) by reaction of 1 with HSnPh 3 . Compound 2 reductively eliminates benzene upon addition of NCMe at 25 °C. The electronic structure of 2 and the mechanism of the reductive elimination of the benzene molecule in its reaction with NCMe were investigated by DFT computational analyses.
