本文描述了在环境温度下通过合并可见光光氧化还原催化和钴催化的四氢喹啉（THQs）、二氢吲哚和其它相关N-杂环的第一无受体脱氢。在有机转化和储氢材料中的潜在应用也得到了展示。初步的机理研究表明，催化循环主要是通过氧化猝灭途径发生的。
Herein, the first acceptorless dehydrogenation of tetrahydroquinolines (THQs), indolines, and other related N-heterocycles, by merging visible-light photoredox catalysis and cobalt catalysis at ambient temperature, is described. The potential applications to organic transformations and hydrogen-storage materials are demonstrated. Primary mechanistic investigations indicate that the catalytic cycle occurs predominantly by an oxidative quenching pathway.
