الملخص
2-Hydrazono-3-phenylquinazolin-4(3H)-ones 11a–i are shown by 15N NMR to exist in DMSO solution predominantly as the imino tautomers B and not the amino tautomers A. 2-Hydrazino-benzimidazole derivative 12 and 2-hydrazino-4,6-dimethylpyrimidine derivative 13 were found to exist predominantly as the amino tautomers.
