1,3,5-Trihydroxyisocyanuric acid (THICA), which serves as an efficient radical-producing catalyst from hydrocarbons, was successfully prepared by two methods. The reaction of O-benzylhydroxyamine with phenyl chloroformate gave formbenzyloxycarbamic acid phenyl ester of which subsequent treatment with dimethylaminopyridine (DMAP) produced 1,3,5-tribenzyloxyisocyanurate leading to THICA by hydrogenation
通过两种方法成功制备了1,3,5-三羟基异氰尿酸(THICA),它是一种有效的由烃类生成自由基的催化剂。的反应ö -benzylhydroxyamine与氯甲酸苯酯,得到其中的随后与二甲基氨基吡啶(DMAP)处理产生1,3,5- tribenzyloxyisocyanurate导致THICA通过氢化用H formbenzyloxycarbamic甲酸苯基酯2在Pd / C。另一种方法涉及由O-苄基羟胺和碳酸二苯酯直接合成1,3,5-三苄氧基异氰脲酸酯。使用THICA作为关键催化剂催化的对甲基茴香醚的好氧氧化,以几乎定量的收率(> 99%)得到了对茴香酸。
