FeCl3 in combination with t-BuOOt-Bu as an oxidant was found to catalyze oxidative coupling of alkylamines with arenes, nitroalkanes, and 1,3-dicarbonylcompounds to give arylmethylamines, β-nitroa...

A stable and recyclable Z-scheme g-C3N4/rGO/BiVO4 heterojunctionphotocatalyst was constructed by a facile two-step hydrothermal procedure. The photocatalyst was used for the synthesis of C-3 formylated indoles from indoles with methanol as an atom-economical formyl source for the first time, and 30% g-C3N4/rGO/BiVO4 exhibited superior photocatalytic efficiency. Quenching experiments showed that the
通过简便的两步水热法构建了一种稳定且可回收的 Z 型 gC 3 N 4 /rGO/BiVO 4异质结光催化剂。该光催化剂首次以甲醇为原子经济型甲酰源,以30% gC 3 N 4 / rGO/BiVO 4为原料,以吲哚为原料合成C-3甲酰化吲哚。表现出优异的光催化效率。猝灭实验表明,光生电子和空穴是实现反应的主要光活性物质。这种甲酰化反应具有优异的官能团耐受性、可重复使用的光催化剂和温和的反应条件等优点。克级合成表明了该策略在实际应用中的未来前景。
