Keywords: | Transfer hydrogenation; Pyrrolidine diphosphine; Asymmetric catalysis; Five-membered chelate; Rhodium | Issue Date: | 2001 | Citation: | Journal of Molecular Catalysis A: Chemical. 168:1-2 (2001) 53-59 | Abstract: | The N-aryl pyrrolidine diphosphine (R,R)-N-phenyl-3,4-bis(diphenylphosphino)pyrrolidine was obtained from natural tartaric acid. Contrary to our preliminary expectations, this new chiral ligand proved to be less selective than the corresponding N-benzyl pyrrolidine diphosphine. An attempted explanation of the observed behaviour based on the stereochemistry of the ligand as shown by X-ray crystallography is presented. | URI: | https://hdl.handle.net/10316/5223 | DOI: | 10.1016/S1381-1169(00)00531-8 | Rights: | openAccess |
