The synthesis of the new compound, bis(trifluoromethyl)dicarbonate, CF3OC(O)OC(O)OCF3, is carried out by reduction of bis(trifluoromethyl)trioxidicarbonate with excess of CO at 0 °C. The product is characterized by IR, Raman, 13C and 19F NMR spectroscopy and its properties are compared with those of the other members of the series CF3OC(O)OxC(O)OCF3, x = 0–3. Single crystals are grown at −25 °C and
通过在0°C下用过量的CO还原双(三氟甲基)三氧化碳酸酯,可以合成新的双(三氟甲基)二碳酸酯CF 3 OC(O)OC(O)OCF 3。该产物用红外,拉曼,13 C和19 F NMR光谱表征,并将其性质与CF 3 OC(O)O x C(O)OCF 3系列其他成员的性质进行比较,x = 0–3 。单晶在−25°C下生长,X射线衍射分析显示,具有C 2的顺式-顺式旋转异构体的堆积对称。DFT计算预测该旋转异构体是最稳定的旋转异构体,并且结构和振动数据也被合理预测。
