  新的Pd（II）双核络合物作为使用芳基硼酸衍生物的氧化-Heck反应的有效催化剂

  摘要：

  已经合成并成功表征了一系列基于螯合二亚胺和桥接二膦或二亚胺配体的新型双核Pd（II）配合物。新络合物的公式为[Pd 2（mbyp）2（DPA）2 ] [PF 6）4（1），[Pd 2（mbyp）2（DPE）2 ]（PF 6）4（2），[ Pd 2（mbyp）2（4,4-byp）2 ]（PF 6）4（3），[Pd 2（mbyp）2（t-pye）2 ]（PF 6）4（4）[mbyp = 4,4'-二甲基-2,2'-联吡啶，DPA = 1,2-双（二苯基膦基）乙炔，DPE = 1,2-双（二苯基膦基）乙烯，4,4-byp = 4,4'-联吡啶，t-ype =反式1,2-双（4-吡啶基）乙烯）]。在芳基硼酸衍生物与各种烯烃的偶联中，已经研究了新络合物的催化活性。获得的结果表明，在游离碱或氧化剂条件下，新配合物在偶联反应中产生有趣的催化活性和化学选择性，以产生共轭加成和heck偶联产物。

  Synthesis and characterization of monochelated carboxylatopalladium(II) complexes with nitrogen-donor chelating ligands. Crystal structures of diacetato(1,10-phenanthroline)- and diacetato(2,9-dimethyl-1,10-phenanthroline)-palladium(II)

  摘要：

  Two series of monochelated carboxylatopalladium(II) complexes of general formula [Pd(L-L)(MeCO2)2] and [Pd(L-L)(CF3CO2)2] [L-L = 1,10-phenanthroline (phen), 2,2'-bipyridine and their substituted derivatives) have been prepared and characterized. The chemical behaviour of the complexes in solution has been studied in different solvents mainly by means of H-1 NMR experiments. These showed that, unlike the acetato complexes, the trifluoroacetato derivatives undergo partial dissociation of the anionic ligand in Me2SO solution at room temperature. A similar behaviour was also observed for the acetato complexes in CD3OD. The signals of the H-2, H-9 protons in the phenanthroline series, and those of H-6, H-6 in the bipyridine one, are excellent probes for the evaluation of the environment of the palladium atom. The crystal structures of [Pd(phen)(MeCO2)2], [Pd(2,9-dmphen)(MeCO2)2].0.40CH2Cl2 and [Pd(2,9-dmphen)(MeCO2)2].0.25CHCl3 (2,9-dmphen=2,9-dimethyl-1,10-phenanthroline) have been determined. The co-ordination geometry around palladium is square planar in all the structures, but significant deviations from the idealized geometry occur in the last two in order to relieve the interligand contacts. These monochelated carboxylatopalladium(II) complexes are active catalysts in carbon monoxide-olefin copolymerization. Some preliminary results on their catalytic activity are also reported.
