Two new bis(diphenylphosphino) amines, N,N-bis(diphenylphosphino) benzidine 1 and N, N-bis(diphenylphosphino)- 3,3-dimethoxybenzidine 2 were prepared by aminolysis. Their corresponding oxides, sulfides and selenides were readily prepared by reaction with hydrogen peroxide, elemental sulfur or grey selenium, respectively. Symmetric dinuclear palladium and platinum complexes were also isolated from the
通过氨解制备了两个新的双(二苯基膦基)胺,N,N-双(二苯基膦基)联苯胺1和N,N-双(二苯基膦基)-3,3-二甲氧基联苯胺2。通过分别与过氧化氢,元素硫或灰色硒反应,可以轻松制备它们相应的氧化物,硫化物和硒化物。还从与[M(cod)Cl-2]的反应中分离出对称的双核钯和铂配合物(M = Pd或Pt,cod =环辛-1,5-二烯)。所有化合物均通过IR和NMR光谱及元素分析进行表征,并通过单晶X射线衍射确定[(Ph2P)(2)N-C6H4-C6H4-N(PPh2)(2)]的结构。还研究了钯配合物在铃木偶联反应中的催化活性。(C)2012 Elsevier BV保留所有权利。
