transfer has not been carefully examined. There only have been selective trials to recognize tautomeric equilibrium of substituted compounds. Unfortunately, conclusions of these studies are often conflicting. Therefore, the aim of this work was to analyze the influence of the factors affecting the tautomeric processes of substituted 1-methyl-2-phenacylbenzimidazoles in solutions of chloroform by spectroscopic
摘要 迄今为止,尚未仔细研究 1-methyl-2-phenacylbenzimidazoles 对质子转移的敏感性。只有选择性试验来识别取代化合物的互变异构平衡。不幸的是,这些研究的结论常常相互矛盾。因此,本工作的目的是通过 1 H 和 13 C NMR 光谱技术分析影响取代的 1-甲基-2-苯并咪唑在氯仿溶液中互变异构过程的因素的影响。只有当互变异构物质的分子包含多个碱性和/或酸性中心时,才会发生复杂的平衡。
