Potentially tautomeric N-sulphonylformamidrazones and models with fixed amide-hydrazone and hydrazide-imide structure have been prepared. The compounds with tautomeric possibilities have been shown to exist only in the amide-hydrazone form by 13C and 1H NMR spectroscopy. The same compounds exist as two rotamers in solution arising hindered rotation around the NCHN single bond.
制备了潜在的互变异构N-磺酰基甲酰胺models和具有固定酰胺-和酰肼-酰亚胺结构的模型。通过13 C和1 H NMR光谱显示,具有互变异构可能性的化合物仅以酰胺-形式存在。相同的化合物以两个旋转异构体的形式存在于溶液中,导致绕NCH= N单键旋转受阻。
