Nickel(II), palladium(II), and copper(II) acetates undertake exchange reaction with the beta-enaminodiones (MeOCO)(RCO)CC(R')NH(2) (R = Me, OMe; R' = Et, EtOCO) in ethanol to give the neutral complexes [M((MeOCO)(RCO)CC(R')NH)(2)] (1-8) [R = Me, R' = Et: M = Ni (1), Pd (2a,b), Cu (3); R = Me, R' = EtOCO: M = Ni (4), Pd (5), Cu (6); R = MeO, R' = Et, M = Pd (7a,b); R = MeO, R' = EtOCO, M = Pd (8a,b)]
镍(II),钯(II)和乙酸铜(II)与β-烯胺二酮(MeOCO)(RCO)CC(R')NH(2)进行交换反应(R = Me,OMe; R'= Et ,EtOCO)在乙醇中得到中性络合物[M((MeOCO)(RCO)CC(R')NH)(2)](1-8)[R = Me,R'= Et:M = Ni(1 ),Pd(2a,b),Cu(3);R = Me,R′= EtOCO:M = Ni(4),Pd(5),Cu(6); M = Ni(4),Pd(5),Cu(6)。R = MeO,R'= Et,M = Pd(7a,b); R = MeO,R′= EtOCO,M = Pd(8a,b)]。在所有情况下,三官能的N,O,O配体均通过亚氨基和一个羰基作为二齿起作用。配合物1-8都是具有正方形平面几何形状的单体。镍和钯配合物在固态中显示出不止一种形式。例如,钯络合物2已合成为两种形式a和b,它们的螯合环的甲氧基
