Hydridorhodacarboranes 3,3-(Ph2RP)2-3-H-3,1,2-RhC2B,H 11-nFn (R = Ph, Me; n = 1, 2, 4) containing F atoms at the B atoms of the π-carborane ligand were synthesized from (Ph2P)3RhCl or (Ph2MeP)3RhCl and nido-7,8-C2B9H12-nFn- (n = 1, 2, 4) salts. Hydridorhodacarboranes 3,3-(Ph2MeP)2-3-H-3,1,2-RhC2B9H 11-nFn readily exchange the H atom at the Rh atom for the Cl atom under the action of CH2Cl2 to give 3,3-(Ph2MeP)2-3-Cl-3,1,2-RhC2B 9H11-nFn. The structures of the 3,3-(Ph3P)2-3-H-3,1,2-RhC2B9H 7F4 and 3,3-(Ph2MeP)2-3-Cl-3,1,2-RhC2B 9H9F9 complexes were determined by X-ray diffraction analysis. Catalytic properties of the rhodacarboranes obtained in hydrosilylation of styrene and phenylacetylene by PhMe2SiH were studied.
