  Gold(I)-triphenylphosphine-arylazoimidazole: Synthesis and spectral (H, C, COSY, HMQC NMR) characterization

  摘要：

  The reaction of [Au(OSO2CF3)(PPh3)] with arylazoimidazole in dichloromethane followed by NH4PF6 leads to [Au(RAaiR')(PPh3)]PF6 (RAaiR' = p-R-N=N-C3H2-NN-1-R'), abbreviated as N,N'/-chelator, where N (imidazole) and N (azo) represent N and N', respectively; R = H (a), Me (b), Cl (c), and R' = Me (I), CH2CH3 (II), CH2Ph (III)]. IR spectra of the complexes show -C=H- and -N=N-stretchings at 1590 and 1370 and at 1100, 755, 695, 545, and 505 cm(-1) due to the presence of the triphenylphosphine ring. The H-1 NMR spectral measurements suggest that methylene (-CH2-) in (RAai)Et gives a complex of the AB type multiplet with a coupling constant of similar to 7.6 Hz while in RAaiCH(2)Ph it shows AB type quartets with coupling constant of av. 7.2 Hz. Considering the arylazoimidazole moity, there are different carbon atoms in the molecule giving different peaks in the C-13 NMR spectrum of the complexes. In the H-1-H-1 COSY spectrum of the present complexes, the absence of any off-diagonal peaks extending from delta = 14.12 and 9.55 ppm confirms their assignment of no proton on N(1) and N(3), respectively. Contour peaks in the H-1-C-13 HMQC spectrum in the present complexes, the absence of any contours at delta = 157.12, 160.76, 155.67, and 157.68-160.2 ppm assign them to the C(2), C(6), C(12), and C(PPh3) carbon atoms, respectively. The solution structure and stereoretentive transformation in each step have been established from the H-1 NMR results.
