Abstract The rate laws for the earliest events in the specific stoichiometric monotransmetalation of heteropolymetallic targets (μ4-O)(amine)4Cu4−xMxX6, where the amine ligand is pyridine (py) or monodentate N,N,-diethylnicotinamide (N), x is 1–3, M is Co or Ni(H2O), X is Cl or Br, by transmetalators M′(NS)2 and their solution adduct formation by reagent Cu(NS)2 in nitrobenzene, where M′ is Co, Ni or Zn and
摘要异多金属靶(μ4-O)(胺)4Cu4-xMxX6的特定化学计量单金属转移的最早事件的速率定律,其中胺配体为吡啶(py)或单齿N,N,-二乙基烟酰胺(N),x为1-3,M为Co或Ni(H2O),X为Cl或Br,由重金属化剂M'(NS)2及其在硝基苯中由试剂Cu(NS)2形成的溶液加合物,其中M'为Co,Ni或Zn和NS是单阴离子S-甲基异丙基肼-碳二硫代酸酯,取决于胺,M,M',x和X.观察到的事件可能是反应前体P1,P2或P3的形成,前体内的金属交换,后继S1,S2或S3配合物或它们的分离产物。将动力学和热力学数据与中性单体目标Cu(ac.ac。)2仅包含氧供体原子。讨论了这些系统中单反金属化特异性和加合物形成的结构机理起源。
