摘要：

Starting from PPh3 (Ph = C6H5), lithium metal, and epoxicyclohexane, (+/-)-2-(diphenylphosphinyl)cyclohexanol (1) was obtained in about 80% yield in a one-pot reaction. Oxidation of the phosphine moiety, either with elemental sulfur or with hydrogen peroxide, gave the corresponding phosphine sulfide 3 reap. oxide 2. The latter compound forms dimers in the solid state. Reaction of the OH fragment of 1 and 3 with chlorodiphenyl phosphine led to new chiral bidentate ligands, bearing a phosphinite donor fragment. Several new transition metal complexes of these ligands were characterized spectroscopically and by X-ray structure analysis. (C) 1997 Elsevier Science S.A.
