Half-sandwich late transition metal complexes based on functionalized carborane ligands

This review describes the recent progress on the research of half-sandwich late transition metal complexes with functionalized carborane ligands. Continuous study on preparation of different types of carborane-based late transition metal complexes is of great interest because of their rich coordination mode, novel reactivity and promising applications in a variety of important fields. The synthetic pathways used for the preparation of half-sandwich complexes with [SS], [PP], [NP], [PS], [CN], [CS] coordination modes are summarized. Diverse reactivities (metal-metal bonding formation, insertion reaction and B-H activation) and catalytic activities (hydrogenation, olefin polymerization, H-2 activation, asymmetric reduction and cross-coupling reaction) are also discussed in this article.
