Uses Rhodium DIPAMP catalysts have shown high activity and enantioselectivity in the asymmetric hydrogenation of enamides, enol acetates and olefins. (R,R)-DIPAMP is a reactant used in the synthesis of Rhodium diphosphine trinuclear complexes. (R, R)-DIPAMP can be used:As a catalyst in the enantioselective [3+2] cycloaddition of γ-substituted allenoates with β-perfluoroalkyl enones and 3-butynoates with electron-deficient olefins to yield substituted cyclopentenes.To prepare its rhodium metal complexes, which are used as catalysts in asymmetric hydrogenation reactions.
