Abstract

Hydridorhodacarboranes 3,3-(Ph2RP)2-3-H-3,1,2-RhC2B9H11−n F n (R=Ph, Me;n=1, 2, 4) containing F atoms at the B atoms of the π-carborane ligand were synthesized from (Ph3P)3RhCl or (Ph2MeP)3RhCl andnido-7,8-C2B9H12−n F n − (n=1, 2, 4) salts. Hydridorhodacarboranes 3,3-(Ph2MeP)2-3-H-3,1,2-RhC2B9H11−n F n 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-RhC2B9H11−n F n . The structures of the 3,3-(Ph3P)2-3-H-3,1,2-RhC2B9H7F4 and 3,3-(Ph2MeP)2-3-Cl-3,1,2-RhC2B9H9F2 complexes were determined by X-ray diffraction analysis. Catalytic properties of the rhodacarbonanes obtained in hydrosilylation of styrene and phenylacetylene by PhMe2SiH were studied.
