Characterization and Molecular Structure of ((PPh3)RhC2B9H11)2, a Phosphinorhodacarborane Dimer Containing Ph-H-B Bridges.
Abstract
The decomposition of Ph(H)(PPh3)2C2B9H11(I) yields (Rh(PPh3)C2B9H11)2 (II) as the only tractable product. The spectral characterization and x-ray molecular structure determination indicate that a terminal B-H bond in (I) has become a Ph-H-B bridge in (II) and (II) is thus a model intermediate in the oxidative addition of a terminal B-H bond to rhodium, the catalytic activity of (II) for the homogeneous hydrogenation of olefins is comparable to that of (I) per rhodium center.
