摘要
The new ligand（1R, 2R）（+）N,N-bis（8-quinolinesulfonylamino）-1,2-diphenylethylene diamine（BQSDA） was synthesized. The 1∶1 chiral crystal was formed from BQSDA with acetone. The crystal belongs to monoclinic, space group P21, a=0.971 7（2） nm, b=0.949 5（10） nm, c=1. 754 2（3） nm, α=γ=90°, β=97.130°, V=1.606（5） nm3, Dc=1.35 g/cm3. There is a hydrogen bond N1—H…O5 between BQSDA and acetone. The ligand has been used as the chiral catalyst in asymmetric hydrogen transfer reaction of acetophenone in a high yield with e. e. up to 66.5%.
