1H-NMR Spectroscopic Assignments of Isomeres to Cyclization Reactions of Benzo-condensed N-HeterocyclesCyclic N-acyl benzazoles show downfield shifts of the aromatic Ha proton at the 1H-n.m.r. spectrum from 0.5 to 1.95 ppm which allows an assignment of possible isomeres and in some cases statements about the tautomerism. The ΔδHa values of 40 different azolo-, azino-, and azepino condensed benzimidazoles are given.
