✦ Synopsis

Asymmetric Hydroformylation of Conjugated Dienes Catalyzed by Chiral Phosphine-Phosphite-Rh(I) Complex.

-Optically active Ξ²,Ξ³-unsaturated aldehydes are obtained in high regio-and enantioselectivities from dienes like (II) and (VI) by the title reaction with chiral (R,S)-BINAPHOS-Rh(I) complex as catalyst. Butadiene (IX) gives achiral products and (E)-and (Z)-pentadienes (XII) and (XIV) form the same major product (XIII) with low enantioselectivities. The reaction conditions are optimized by variation of the H2/CO pressure (1:1 mixtures) and the temperature. -(HORIUCHI,
