reaction of Cu(NO3)2 ⋅ 3H2O with PNPNTPh‐Ph in the presence of pyridine the complexes [Cu(O2PPh2)2(Py)2(H2O)] (3), [Cu(O2PPh2)(Py)2(NO3)]2 (4), and [Cu(Py)4(NO3)2].Py (5), were obtained, 2, 3, and 4 contain diphenyl‐phosphinate ligands. The underlying redox reaction of the ligand and Cu(II) yielding the oxidised ligands observed in the by‐products and the Cu(I) product complex was further studied using
新的Cu(I)络合物[Cu(PNP NTPh- Ph)Cl](1)包含三齿PNP钳形配体N,N'-双(二苯基膦基)-2,6-二氨基-4-苯基-1,3,从[Cu(SMe 2)Cl] n与作为醚溶剂化物1的配体的反应中获得了5-三嗪。从包含配体和Cu(II)前体CuCl 2的反应混合物中独立获得0.5Et 2 O. 1 。2H 2 O(产率为50%)以及Cu(II)配位聚合物[Cu(O 2 PPh 2)2 ] n(2)。选自Cu(NO的反应3)2 ⋅3H 2 ö与PNP NTPh -Ph在吡啶的存在下,复合物[Cu(O 2 PPH 2)2(PY)2(H 2 O)](3),[ Cu(O 2 PPh 2)(Py)2(NO 3)] 2(4)和[Cu(Py)4(NO 3)2 ] 。PY(5),得到,2,3,和4个包含二苯基次膦酸酯配体。使用电化学和紫外可见光谱电化学技术进一步研究了副产物和Cu(I)
