L. Dahlenburg et A. Kaunert, CHIRAL BISPHOSPHATES - 7 - -CYCLOPENTANE-1,2-DIYL-BIS(PHOSPHONOUSDICHLORIDE), (1S,2S)-C5H8(PCL2)(2) - A VERSATILE OPTICALLY-ACTIVE REAGENT, EUROPEAN JOURNAL OF INORGANIC CHEMISTRY, (7), 1998, pp. 885-887
Treatment of (1S,2S)-C5H8(PH2)(2) (1) with OC(OCCl3)(2) gave (1S,2S)C5
H8(PCl2)(2) (2) as the first example of an optically active bis(phosph
onous dichloride). 2 was converted to (1S,2S)-C5H8(PX2)(2) [PX2 = P(OM
e)(2) (3), P(OPh)(2) (4), P[OCH(Me)Et-(S)](2) (5), P[2-OC10H6C10H6O-2'
-(R)] (6), P(NC4H8O-cyclo)(2) (7), P(C6H11-cyclo)(2) (8)] by reactions
with oxygen, nitrogen, and carbon nucleophiles.
