reaction energies for the direct fluorination of ethylene and propylene carbonate were calculated at the reliable G3 level of theory. The excellent decomposition stability of the cyclic carbonates against high fluorine and HF concentrations also qualifies them as good solvents for direct fluorination processes, especially for ionic substrates. In this respect, the direct fluorination of the inorganic salt
测试了用于有机和无机物质直接氟化的新型微型反应器。该反应堆由带镍的铜块组成,该铜块具有机械加工的1毫米通道,并配有主动冷却系统。描述了碳酸亚乙酯和碳酸亚丙酯的直接氟化。对于氟化碳酸亚丙酯,测定了各种氟化异构体的NMR数据。乙烯和碳酸亚丙酯直接氟化的吉布斯反应能是在可靠的G3理论水平下计算的。环状碳酸酯对高氟和高HF浓度具有出色的分解稳定性,也使它们成为直接氟化工艺(尤其是离子底物)的良好溶剂。在这方面,无机盐的直接氟化介绍了环状碳酸酯中的closo -K 2 [B 12 H 12 ]。
