Reaction diversity of Ni—S bonds in nickel(Ⅱ)-thiolate complexes and synthesis of organometallic compounds to mimick the active site of nickel containing enzymes

报道了利用镍(Ⅱ)-硫醇阴离子配合物[Ni—(S)4]和Fe3(CO)12反应制备有机硫配体桥联的多核Ni—Fe2配合物[Ni{(C6H4S2)2(CH2)3}(μ-S,S')Fe2(CO)6]和[Ni{(CH3C6H3S2)2(C3OH)}(μ-S,S')Fe2(CO)6]。其中后者中引入了羟基功能化基团,以便将其负载到改性的电极材料上研究其还原产物的电催化性能。通过核磁共振、红外、质谱和晶体结构测定等手段对相关化合物进行了表征。

The syntheses of thiolate bridged multinuclear [ Ni＇Fe21 complexes, [ Ni{ （ C6H4S2 ）2 （ CH2 ）3 } （ μ-S, S＇） Fe2（CO）6] and [Ni{（CH3C6H3S2）2（C3OH）} （μ-S,S＇） Fe2 （CO） 6 ] were reported from the reaction of Ni （ Ⅱ ） -thio- late complexes with Fe3 （CO）12. Functional OH group was in- troduced into [ Ni{ （CH3C6H3S2）5 （C3OH） I （ μ-S, S＇） Fe2 （CO） 6 ] so that it can be grafted onto modified electrodes to investigate the electro-catalytic property of reduced species of [Ni/（CH3C6H3S2）2（C3OH）} （μ-S,S＇）Fe2（CO）6].The new compounds were confirmed by NMR, IR, MS and X-ray crystallography.
