Nitrogen NMR studies on some fused ring N-heterocycles

Abstract

^(15)N and^(14)N NMR data are reported for a number of fused ring N-heterocycles.^(14)N line widths,^(15)N-^1H couplings and nitrogen shielding additivity rales are used for^(15)N signal assignments. The results obtained lead to some progress in the generalization of the effects of nitrogen-nitrogen interactions on nitrogen shieldings.
