摘要
Described is the preparation, resolution, and absolute configuration of a new axially chiral monodentate phosphine ligand. The chirality of the ligand is derived from restricted rotation about a central N-imide-C-aryl bond, resulting in enantiomeric atropisomers that are stable and separable up to > 120 degreesC. Finally, the ability of the new axially chiral phosphine ligand is demonstrated in a Pd-catalyzed allylic alkylation reaction. (C) 2001 Elsevier Science Ltd. All rights reserved.
