Abstract

Electrocatalytic dehydrogenative C(sp)-H/C(sp)-H cross-coupling of tetrahydroisoquinolines with terminal alkynes has been achieved in a continuous-flow microreactor through 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO)/copper relay catalysis. The reaction is easily scalable and requires low concentration of supporting electrolyte and no external chemical oxidants or ligands, providing straightforward and sustainable access to 2-functionalized tetrahydroisoquinolines.

摘要

通过2,2,6,6-四甲基哌啶1-氧基（TEMPO）/铜接力催化，在连续流动微反应器中实现了四氢异喹啉与末端炔烃的电催化脱氢C(sp)-H/C(sp)-H交叉偶联。该反应易于放大，所需支持电解质浓度低，无需外部化学氧化剂或配体，为制备2-官能化四氢异喹啉提供了直接且可持续的方法。
