Diheteroarylmethanes. 5. E-Z isomerism of carbanions substituted by 1,3-Azoles: 13C and 15N π-charge/shift relationships as source for mapping charge and ranking the electron-withdrawing power of heterocycles

Previously proposed π-charge/shift relationships have been applied to 13C and 15N shifts of the carbanions of 2-benzylazoles (thiazole, oxazole, and imidazole), their corresponding benzo-fused analogs, and bis(2-azolyl)methanes (azol
