双核钼/钨金属键有机化合物的反应化学研究

着重总结了我们研究组近几年来对M-M(M=Mo,W)金属单键化合物(η^5-RC5H4)2M2(CO)6,M=M金属双键化合物(η^5-RC5H4)2M2(CO)2(μ-EPh)2(E=S,Se,Te)及M≡M金属三键化合物(η^5-RC5H4)2M2(CO)4的反应化学所取得的系列成果。该系列成果清楚地表明这三类典型的金属键有机化合物可分别同多种无机、有机以及金属有机试剂发生涉及金属键加成、金属键断裂以及金属键上配体的消除和环戊二烯基配体上有机官能团的转化等一系列有趣反应。这些反应不仅有重要理论意义而且被广泛地用在新型金属有机和原子簇化合物的合成上。

Reaction studies on dinuclear Mo/W metal-metal bonded organometallic compounds

In this article we summarize a series of scientific results obtained in recent years through our study on chemical reactions of M-M(M=Mo, W) singly-bonded compounds (η^5-RC5H4)2M2(CO)6, M=M doubly-bonded compounds (η^5-RC5H4)2M2(CO)2(μ-EPh)2(E=S, Se, Te) and M≡M triply- bonded compounds (η^5-RC5H4)2M2(CO)4. These results clearly show that the three types of metal-metal bonded organometallic compounds mentioned above can react with a wide variety of inorganic, organic and organometallic reagents. These studied reactions may involve addition to or cleavage of metal-metal bonds, elimination of the ligands attached to metal-metal bond and/or transformations of the organic functionalities on cyclopentadienyl rings. They are of importance in both theory and practical applications in synthesis of new types of organometallic compounds and cluster complexes.
