several their cobalt(III) complexes were prepared and characterized. The RS(N) isomers of trans-[CoCl2(pp- or SS(C)-pp-232PNNP)]+ were formed by oxidation of cobalt(II) complexes of these ligands in dichloromethane with chlorine, while the RR,SS(N), and RR(N) isomers of the pp-232PNNP and SS(C)-pp-232PNNP complexes, respectively, were derived from the corresponding carbonato complexes and hydrochloric
两个新的四齿膦配体 1,1,11,11-四苯基-4,8-二氮杂-1,11-二磷十一烷 (pp-232PNNP) 和 (3S,9S)-3,9-二甲基-1,1,11,制备并表征了 11-四苯基-4,8-二氮杂-1,11-二磷十一烷 (SS(C)-pp-232PNNP) 及其几种钴 (III) 配合物。反式-[CoCl2(pp- 或 SS(C)-pp-232PNNP)]+ 的 RS(N) 异构体是通过这些配体的钴 (II) 配合物在二氯甲烷中用氯氧化形成的,而 RR,SS( N) 和 pp-232PNNP 和 SS(C)-pp-232PNNP 复合物的 RR(N) 异构体分别来自相应的碳酸根复合物和盐酸。[Co(OO)(pp- 或 SS(C)-pp-232PNNP)]n+ (O-O= CO32-, C2O42-, C5H7O2-) 复合物仅产生顺式β异构体。根据吸收、圆二色性和核磁共振光谱讨论了配合物的立体化学。
