The Synthesis of a Mixed-Metal, Bimetallic, Monocarbon Metallocarborane by Polyhedral Expansion

摘要

Addition of Na(+)C5H5(-) and NiBr2:2C2H4(OCH3)2 to ((CH3)4N)((pi-C5H5)Co(III)-(pi-CB7H8)) previously reduced with sodium naphthalide formed a new bimetallic mixed-metal monocarbon metallocarborane (pi-C5H5)Co(III)(pi-CB7H8)Ni(IV)(pi-C5H5), isolated in at least four isomeric forms. This represents a new extension of the polyhedral expansion reaction to monocarbon metallocarboranes. (Author)
