A single-site chromium catecholate POP (catPOP A(2)B(1)) was synthesized and characterized via AT-IR, XAS, and EPR spectroscopy. The well-defined, four-coordinate, 11-electron Cr(III) centers bound to catecholate POP were demonstrated to be active hydrogenation catalysts for nonpolar unsaturated organic substrates under mild conditions (5 mol % of Cr, 200 psi of H-2, 60 degrees C). This material constitutes the first example of a well-defined, supported organometallic chromium hydrogenation precatalyst.
