使用BINAPHOS-Rh-I络合物作为催化剂{(R,S)-BINAPHOS = [(R)-2-二苯基膦基-1,1 '-二萘-2'-基] [(S)-1,1 '-二萘-2,2'-二基]-亚磷酸酯},共轭二烯如乙烯基环己烯、(E)-苯基-丁-1,3-二烯和4-甲基-戊-1,3-二烯的不对称氢化得到光学活性β,γ-不饱和醛的高区域选择性(81-91%)和对映选择性(84- 97%ee)。
Asymmetric hydroformylation of conjugated dienes such as vinylcyclohexene, (E)-phenyl-buta-1,3-diene and 4-methyl-penta-1,3-diene using BINAPHOS-Rh-I 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 beta,gamma-unsaturated aldehydes in high regio- (81-91%) and enantio-selectivities (84-97% ee).
