摘要：

Optically active 1, 1'-binaphthols (BINOLS) substituted at the 4,4'; 6,6' and 4,4',6,6' positions with perfluoroalkyl groups have been synthesized. Asymmetric diethylzinc and triethyl aluminum addition to aryl aldehydes in a fluorous biphasic system catalyzed by these perfluoroalkyl-BINOL-titanium complexes have been accomplished with good enantiomeric excess obtained.
