1,1′-Bis[6-(trifluoromethyl])benzotriazolyl] carbonate (BTBC) was prepared from 1-hydroxy-6-trifluoromethylbenzotriazole and trichloromethyl chloroformate (trichloromethyl carbonochloridate). The reaclion of BTBC and alcohols afforded the corresponding active carbonates which were converted into the corresponding carbamates and carbonates.
1,1′-双[6-(三氟甲基)苯并三唑基]碳酸酯(BTBC)是由1-羟基-6-三氟甲基苯并三唑和三氯甲基氯甲酸酯(三氯甲基碳酸氯化物)合成的。BTBC与醇的反应生成相应的活性碳酸酯,这些碳酸酯进一步转化为相应的氨基甲酸酯和碳酸酯。
