Oligophosphine Ligands, XXXIX. (1S,2S)-trans-Cyclopentane-1,2-diyl-bis(phosphine), C5H8(PH2)2, by Reduction of a Diastereomerically Pure Cyclopentanediyl-bis(dioxaphospholane)

The title compound (S,S)-2, has been obtained by reduction with Li of the cyclopentane-1,2-diyl-bis(1',3',2'-dioxaphospholane)(1S,2S)-trans-C5H82, (S,S)-1, which itself was isolated in diastereomerically pure form (X-ray structure analysis) from the reaction betwen rac,trans-C5H8(PCl2)2 and (2R,3R)-(+)-diisopropyl tartrate.Cleavage of (S,S)-1 with PCl3 yielded an unseparable mixture of (1S,2S)-trans-C5H8(PCl2)2 and (4R,5R)-ClP2. - Keywords: Chiral Bis(phosphine), Reduction of P-O, X-Ray, Mass Spectra, NMR Spectra
