The synthesis of paracetamol still relies on multistep protocols involving the utilization of a stoichiometric amount of oxidizing/reducing or other corrosive agents. Herein we report a regioselective electrochemical Ritter-type reaction at the C(sp2)–H of unprotected phenol toward the environmentally benign and direct synthesis of paracetamol. The reaction proceeds under exogenous oxidant- and catalyst-free
扑热息痛的合成仍然依赖于涉及使用化学计量的氧化/还原剂或其他腐蚀剂的多步方案。在这里,我们报告了在未受保护的苯酚的 C(sp 2 )-H 上的区域选择性电化学 Ritter 型反应,对环境无害且直接合成扑热息痛。该反应在无外源氧化剂和无催化剂条件下进行。该协议是可扩展的,可以部署到各种酚类,并为扑热息痛的合成提供可持续的替代方案。
