摘要:

One bond and long range JCH coupling constants for a series of 2-quinolone derivatives are described. The spectra of the parent compound shows considerable second order character at both 15 MHz and 90 MHz in CDCl3and in DMSO-d6solution, which has been discussed. The variations in the coupling patterns resulting from the fusion of the lactam ring and change of heteroatom are highlighted.
