investigated by UV-, IR- and NMR spectroscopic techniques. All of these compounds were found to exist predominantly, if not exclusively, in the lactam (carboxamide, 1,2-dihydro-2-oxoquinoline) form. No tautomeric lactim (iminol, azaphenol) structure was detected. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008).
                                    合成了 12 种定制的模型 3-
氟-2(1H)-
喹啉酮,以便通过紫外、红外和核磁共振光谱技术进行研究。发现所有这些化合物主要以内酰胺(甲酰胺,1,2-二氢-2-氧
喹啉)形式存在,如果不是唯一的话。未检测到互变内酯(
亚胺醇、氮杂
苯酚)结构。((C) Wiley-
