SuFEx chemistry has recently evolved as next-generation click chemistry. However, in most SuFEx syntheses, additional reagents/catalysts and carefully controlled conditions are still needed. Here, we aim to further generalize S(VI) exchange chemistry, using 4-nitrophenyl phenylmethanesulfonate as example, in which the nitrophenolate group is exchanged for a wide range of (substituted) phenols and alkyl
SuFEx 化学最近发展成为下一代点击化学。然而,在大多数 SuFEx 合成中,仍然需要额外的试剂/催化剂和仔细控制的条件。在这里,我们的目标是进一步推广 S(VI) 交换化学,以 4-硝基苯基苯甲磺酸盐为例,其中硝基苯酚盐基团被交换为广泛的(取代的)酚类和烷基醇。在环境条件下在 10 分钟内达到定量产量,并且仅需要通过二氧化硅过滤作为后处理。
