Reactions between CpFe(CO) 2 SPh and M(CO) 5 THF (M = Cr, Mo, and W) in a mixture of benzene and THF at room temperature afforded compounds of the type CpFe(CO) 2 (μ‐SPh)M(CO) 5 ( 1 ) [M = Cr ( 1a ), Mo ( 1b ), and W ( 1c )] in high yield. However, migration of the thiolato ligand occurred during reactions between CpM(CO) x SPh (M = Fe, x = 2; M = Mo and W, x = 3) and Fe 2 (CO) 9 forming compounds [Fe(μ‐SPh)(CO) 3 ] 2 and [CpM(CO) x ] 2 (M = Fe, x = 2; M = Mo and W, x = 3). Single‐crystal X‐ray diffraction analyses reveal that 1c is a single thiolato‐bridged hererobimetallic compound without a metal−metal bond. Metal−metal bond formation in compounds 1 by decarbonylation under thermal or photolytic condition was not observed. Reactions between compounds 1 and PPh 3 produced CpFe(CO) 2 SPh and PPh 3 M(CO) 5 (M = Cr, Mo, and W) by M−S bond cleavage in 1 .
