Abstract: An overview of the syntheses, structures, and reactivity
of the compounds formed by the incorporation of a number of d- and f-block
metals into C2B4- and C2B9-carborane
cages have been presented. In addition,the development of a safe, bench-scale
preparation of the toxic and commercially unavailable polyhedral borane
synthon, namely pentaborane(9), has also been described. Thus, this
report discusses the latest developments leading to a sys- tematic synthetic
approach to a number of carborane precursors and the subsequent reaction
chemistry in the formation of a number of �carbons-apart �metallacarboranes.
