Synthesis and structures of heterometallic trinuclear clusters [CpFe(CO)₂]₂(µ₃-S₂)W(CO)₅ and Cp₂Fe₂(CO)₃(µ-CO)(µ₃-S)W(CO)₅ and kinetic study of migration of the W(CO)₅ moiety in the disulfido complex

Abstract

The reaction of CpFe(CO)₂Br, NaSH and W(CO)₅(THF) gave two Fe₂W clusters, one with a µ₃-S₂ and the other with a µ₃-S; in the former cluster W(CO)₅ moiety migration on the disulfido ligand was observed by variable-temperature ¹H NMR spectroscopy.
