摘要: A series of complexes composition trans-[PtCl2L(PEt3)], where L is an 8-substituted quinoline, have been studied by 1H and 31P NMR spectroscopic methods [substitnent = CHO, CH3, HC(CH3)2, CHBr2]. The protons the substitnent at 8-position couple to 195Pt with values for nJ(195Pt1H) which are too large five-bond coupling constants, thereby suggesting a Pt…HC interaction. Two-dimensional were used purposes assignment also defining chemical exchange process. shape satellite lines in spectra vary magnetic field strength owing CSA relaxation 195Pt.
