(R,R)-DIPAMP Chemical Properties,Uses,Production

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 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.

Uses

(R,R)-DIPAMP is a reactant used in the synthesis of Rhodium diphosphine trinuclear complexes.
