(R,R)-DIPAMP Usage And Synthesis

Uses	Rhodium DIPAMP catalysts have shown high activity and enantioselectivity in the asymmetric hydrogenation of enamides, enol acetates and olefins.
Chemical Properties	White crystalline powder
Uses	(R,R)-DIPAMP is a reactant used in the synthesis of Rhodium diphosphine trinuclear complexes.
Uses	(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.
