摘要

一种含有二氰乙烯基受体的咔唑基光催化剂（MD）具有优异的氧化还原电位，可用于合成吲哚基二甲基甲烷和2取代苯并咪唑的可持续光催化方法。该工艺通过MD在可见光下的氧化猝灭循环进行操作，不需要外部氧化剂或金属催化剂。该方法具有良好的官能团耐受性、高选择性和环境友好性，为绿色光催化的研究做出了重要贡献。

Unveiling a carbazole-based photocatalyst for visible-light-driven synthesis of indolyl diarylmethanes and 2-benzimidazoles†

A carbazole-based photocatalyst (MD) incorporating a dicyanovinyl acceptor and exhibiting superior redox potential has been demonstrated for a sustainable photocatalytic approach to synthesize indolyl diarylmethanes and 2-substituted benzimidazoles. This protocol operates via an oxidative quenching cycle of MD under visible light, eliminating the need for external oxidants or metal catalysts. The methodology offers excellent functional group tolerance, high selectivity, and environmentally friendly conditions, making it a valuable contribution to green photocatalysis.
