Abstract
Abstract Syntheses of new cationic chiral pyrrolidinephosphine–rhodium complexes and their application to the asymmetric hydrogenation of itaconic acid were described. Thus, PPPM-, BZPPM-, FPPM- and BPPM-Rh+ in the presence of triethylamine gave S-(−)-methylsuccinic acid in 87.1, 88.9, 94.2 and 93.6% optical yields respectively.
