In the present work the synthesis of the trifluoromethoxyl fluoroformyl anhydride is presented for the first time. Two strategies were employed to obtain CF3OC(O)OC(O)F: the thermal decomposition of CF3OC(O)OOOC(O)F in excess of CO, and the reaction between CF3OC(O)OOC(O)F, FC(O)OOC(O)F and CO. A mechanism was proposed taking into account reaction rates and thermal stability of the intermediates. DFT
在本工作中,首次提出了三氟甲氧基氟甲酸酐的合成方法。采取两种策略来获得CF 3 OC(O)OC(O)F:CF 3 OC(O)OOOC(O)F在过量CO中的热分解,以及CF 3 OC(O)OOC( O)F,FC(O)OOC(O)F和CO。考虑到反应速率和中间体的热稳定性,提出了一种机理。使用D3在B3LYP / 6-311 + G *水平上的DFT计算来探索该分子的构象空间和室温下构象子的相对种群,并模拟实验振动光谱。该分子完善了不对称氧键酰基化合物CF 3 OC(O)O x的家族X = 1-3的C(O)F 。
