ethylenediamine (en), whereas the diphosphine derivatives trans-[OsCl2(dppf)(NN)] (NN = en (3), bn (4; bn = 1,4-butanediamine)) and trans-[OsCl2(dpbp)(en)] (5) were obtained from 1a, dppf or dpbp, and the corresponding NN ligand in CH2Cl2 or toluene. An X-ray diffraction study has been provided for 3. The isolation of the chiral derivatives trans-[OsCl2(diphosphine)((R,R)-dpen)] (diphosphine = dppf (6), dpbp (7)
通过[OsCl 2(PPh 3)3 ](1a)与乙二胺(en)反应制得O络合物反式-[OsCl 2(PPh 3)2(en)](2),而二膦衍生物反式-[[ OSCL 2(DPPF)(NN)](NN = EN(3),BN(4 ; BN = 1,4-丁二胺))和反式- [OSCL 2(DPBP)(烯)](5从获得)1A,dppf或dpbp,以及CH 2 Cl 2中相应的NN配体或甲苯。X射线衍射研究已经提供了3。分离了手性衍生物反式-[OsCl 2(diphosphine)((R,R)-dpen)](diphosphine = dppf(6),dpbp(7),(R,R)-skewphos(8))使1a与二膦和(R,R)-dpen在甲苯中反应。所述前体[Os中治疗2氯4(P(米间-甲苯基)3)5 ](图1b)带连接,得到[OSCL2(P(米间-甲苯基)3)2(烯)](9),而反应1B与DPPB和Ñ,Ñ
