3-benzothiazole reacts with anilines to form the corresponding trifluoromethyl-substituted alcohols. The reaction regioselectivity (ortho/para) was shown to depend strongly on the structure of the aniline. meta-Substituted anilines tend to form the corresponding ortho-substituted products, in contrary to the previous literature data. anilines - Friedel-Crafts alkylation - ortho/para-substitution - trifluoromethyl
2-三氟乙酰基-1,3-苯并噻唑与苯胺反应形成相应的三氟甲基取代的醇。反应区域选择性(邻位/对位)显示出强烈依赖于苯胺的结构。与先前的文献数据相反,间位取代的苯胺倾向于形成相应的邻位取代的产物。 苯胺-Friedel-Crafts烷基化-邻位/对位取代-三氟甲基醇-1,3-苯并噻唑
