Article abstract of DOI:10.1016/S0040-4039(00)79088-5

The synthesis of (R, R)DIPAMP ruthenium bis (2-methylallyl) 2 and halogeno derivative (R, R) DIPAMPRu₂X₂ 3 complexes is presented, which uses the easily available from (COD)₂Ru(2-methylallyl)₂ 1. These new catalysts were found to be effective for asymmetric hydrogenation of both olefins and keto groups (35-80% ee).
