摘要:根据可持续绿色发展的要求,高效绿色合成氟化工产品是必然趋势.在这项工作中,我们首次使用离子液体作为重要的含氟化学反应--六氟丙烯二聚反应的有效催化剂.系统研究了具有不同空间位置,取代基和亲核阴离子的离子液体对六氟丙烯二聚催化性能的影响.结果表明,强亲核性三取代硫氰酸酯咪唑离子液体[C 6 Mmim][Scn]在最佳反应条件下活性最高,转换频率(Tof)为108.36 H-1选择性为97.96%.与传统的金属盐催化剂体系相比,离子液体的催化活性提高了一倍.此外,基于xps分析结果和密度泛函理论(Dft),提出了一种可能的反应机理.离子液体的有效催化活性主要归因于阴离子的强亲核性和阳离子与阴离子之间的弱相互作用.该工作将成功为六氟丙烯二聚提供一条绿色合成路线,进一步促进氟化学反应的高效化和绿色化.
