Abstract The reaction of the multidentate ligand N-(2-(aryldiazenyl)phenyl)picolinamide, HL (3a, 3b and 3c) [HL is ArN = NC6H4NHC(O)Py, where Ar is C6H5 for HL1 (3a), p-MeC6H4 for HL2 (3b) or p-ClC6H4 for HL3 (3c), and Py stands for pyridyl], with Cu(CH3COO)2·H2O and Na2PdCl4 separately afforded the complexes [(L)2Cu] (4a, 4b and 4c) and [(L)PdCl] (5a, 5b and 5c) respectively, where the deprotonated
摘要多齿配体N-(2-(芳基二氮烯基)苯基)吡啶啉酰胺与HL(3a,3b和3c)的反应[HL为ArN = NC6H4NHC(O)Py,其中HL1(3a)的Ar为C6H5,p- HL2(3b)的MeC6H4或HL3(3c)的p-ClC6H4,Py代表吡啶基],Cu(CH3COO)2·H2O和Na2PdCl4分别提供复合物[(L)2Cu](4a,4b和4c)和[(L)PdCl](5a,5b和5c),分别去质子化的配体L-以三齿(N,N,N)方式结合铜(II)和钯(II)。测定[(L3)2Cu](4c)和[(L1)PdCl](5a)的X射线结构以确认分子结构。新合成的络合物4a对醇氧化成相应的羰基化合物和有机硫醚氧化成亚砜和砜具有催化活性,而络合物5a是铃木和Heck反应的活性催化剂。
