摘要：
Chiral diphosphite ligands L-1-L-3 were prepared by the reaction of (1S,5S,6R)-(cis,trans)-spiro[4.4]nonane-1,6-diol with chlorophosphites. These ligands were tested in the rhodium catalyzed hydroformylation of styrene and enantioselectivities up to 69% were achieved. High regioselectivities (97%) to 2-phenylpropanal and high yields (98%) were obtained under mild reaction conditions. The influence of reaction conditions is also discussed.
