The invention relates to novel trans-1,2-bis(dihalo- phosphino)-cycloalkanes (I) wherein the alkane moiety contains from 3 to 12 carbon atoms, trans-1,2-bis[di(X)-phosphino]cycloalkanes (II) wherein the alkane moiety contains from 3 to 12 carbon atoms and X is either hydrocarbyl or alkoxy and the resolved enantiometers of (II). Compounds (I) are produced by reacting a C3 to C12 cyclic olefin with a trivalent phosporous compound of the formula PX3 wherein X is chlorine or bromine in the presence of elemental phophorous. Compounds (I) are converted to compounds (II) by reaction with an (X)-containing carbon nucleophile.
本发明涉及新型反式-1,2-双(二卤代膦基)环烷烃(I)(其中烷基含有 3 至 12 个碳原子)、反式-1,2-双[二(X)-膦基]环烷烃(II)(其中烷基含有 3 至 12 个碳原子,X 为烃基或烷氧基)以及(II)的解析对映体。化合物(I)是通过 C3 至 C12 环状烯烃与式 PX3 的三价多孔化合物(其中 X 为氯或溴)在多孔元素存在下发生反应而制得。化合物(I)通过与含(X)碳亲核物反应转化为化合物(II)。
