Abstract

Asymmetric hydroformylation of conjugated dienes such as vinylcyclohexene,(E)-phenyl- buta-1, 3-diene and 4-methyl-penta-1, 3-diene using BINAPHOS–RhI complexes as catalysts {(R, S)-BINAPHOS=[(R)-2-diphenylphosphino-1, 1′-dinaphthalen-2′-yl][(S)-1, 1′-dinaphthalene-2, 2′-diyl]-phosphite} gives optically active β, γ-unsaturated aldehydes in high regio-(81–91%) and enantio-selectivities (84–97% ee).
