A series of rhodaboratranes [{o(Ph2P)C6H 4}3BRhHn(CO)]m (1, n = 1, m = 0; 4, n = 0, m = +1; 5, n = 0, m = -1) with different electron charges ranging from -1 to +1 have been synthesized. X-ray diffraction, IR, NMR, and DFT calculation studies have demonstrated that the σ-acceptor borane ligand produces a unique electron distribution in these systems and significantly weakens the Rh-L bond (L = CO, PR3) trans to the boron. The reversible CO/PR 3 (R = Me or Ph) substitution reactions of 1 and 5 are attributed to these properties.
