Abstract
The N-aryl pyrrolidine diphosphine (R. R)-N-phenyl-3,4-bis(diphenylphosphin o) pyrrolidine was obtained from natural tartaric acid. Contrary to our pre liminary expectations, this new chiral ligand proved to be less selective t han the corresponding N-benzyl pyrrolidine diphosphine. An attempted explan ation of the observed behaviour based on the stereochemistry of the ligand as shown by X-ray crystallography is presented. (C) 2001 Elsevier Science B .V. All rights reserved.
