- 中文摘要: Silver triflate [AgOTf] assisted de-bromination gives [Ni(dppm/dppe/(PPh3)2) (Otf)2], which on reaction with 4,4¢-bpy and gold(I) phosphines in dichloromethane medium by the self assemble technique leads to [{(L)Ni}{(4,4-bpy)Au(PPh3)}2](Otf)4, (1,2,3) [{(L)Ni(4,4-bpy)}4](Otf)8, (4,5,6) [L = dppm/ dppe/(PPh3)2 = diphenyl phosphino-methane, -ethane, bis-triphenylphosphine, OSO2CF3 is the triflate anion]. The maximum molecular peak of the corresponding molecule is observed in the ESI mass spectrum. Ir spectra of the complexes show -C=C-, -C=N-, as well as phosphine stretching. The 1H NMR spectra as well as 31P (1H)NMR suggest solution stereochemistry, proton movement, and phosphorus proton interaction. Considering all the moieties, there are a lot of carbon atoms in the molecule reflected by the 13C NMR spectrum. In the 1H-1H COSY spectrum of the present complexes and contour peaks in the 1H-13C HMQC spectrum, we assign the solution structure and stereoretentive transformation in each step.
