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
本文描述了四氢喹啉(THQs),二氢吲哚和其他相关的N-杂环在环境温度下的首次无受体脱氢,方法是合并可见光光氧化还原催化和钴催化。演示了在有机转化和储氢材料中的潜在应用。初步的机械研究表明,催化循环主要通过氧化淬灭途径发生。
