## Abstract The ^13^Cβnmr study was carried out for the tautomerism of the 3β(arylhydrazono)methylβ2βoxoβ1,2βdihyβdroquinoxalines 1aβg and 2aβe between the hydrazone imine A and diazenylenamine B forms, providing the carbon chemical shifts for the tautomers A and B of compounds 1aβg and 2aβe. The c
