Abstract:

The ⅦB group organometallic compounds of Mn or Re have been widely investigated on the synthesis, characterization, possible reactivity properties and catalytic activities. Compared to the use of NHCs as ligands, the exploration in the field of carbene dithiocarboxylate(NHC·CS2) coordination with metal is very lack. Herein reported the synthesis, characterization, reactivity and electrochemical studies of a series of Mn and Re organometallic complexes containing NHC·CS2 ligands, concluding three mononuclear complexes and three dinuclear complexes. Those compounds were characterized by elemental analysis, IR, 1H NMR and 13C NMR. Compared to R3P·CS2 ligands, Mn-Re dinuclear organometallic complexes containing NHC·CS2 ligands showed different reactivity. The electrochemical studies of [MnRe(CO)6(μ-H){μ-CH3SC(S)·IMes2}] were explored, and the results showed it possesses the potential catalytic property for proton reduction of acetic acid to give hydrogen under electrochemical conditions, which may be considered as a model in the research of the active site of [Fe-Fe] hydrogenases.

Key words: NHC·CS2, Mn-Re dinuclear complex, Mononuclear complex, Electrochemical property
