Preserved Fulltext
A readily prepared chiral pyrrolylphosphinite has been found highly efficient for Rh(I) catalyzed asymmetric hydroformylation of 1,1-disubstituted olefins. Chiral linear aldehydes have been synthesized with high productivity (turnover number (TON) up to 8900), excellent regioselectivity, and good to high chemo-and enantio-selectivites (71%~86% ee). The reaction features ready catalyst preparation and wide functional group tolerance, thus will be of practical value in the use of asymmetric
