Abstract The review covers the synthesis, structural features and catalytic activity of rhoda- and iridacarborane halide complexes containing monoanionic dicarbollide [L-C2B9H10]− (L = SMe2, NMe3) and tricarbollide [tBuHN-C3B8H10]− ligands. These complexes are structural analogs of the well-known cyclopentadienyl complexes [Cp*MCl2]2, which are widely used as catalysts for various C–H activation processes. Although the search for applications of halide metallacarboranes started not a long time ago, they have already proved to be efficient catalysts for oxidative coupling of benzoic acids with internal alkynes and reductive amination of carbonyl compounds without external hydrogen source. The influence of substituents in the carborane cage on the structure and catalytic activity is also discussed.
