Manipulating selective amine transformation pathways via cocatalyst-modified monolayer ZnIn2S4 photocatalysts

Abstract

Semiconductor-based artificial photoredox-catalyzed organic synthesis offers a promising and green opportunity to harness solar energy for green organic chemistry. However, the precise manipulation of product selectivity over semiconductor-based photocatalysts for selective organic synthesis remains challenging. In this work, we report the rational preparation and application of two kinds of cocatalyst, (RuS2 or Cu2S)-decorated monolayer ZnIn2S4, for the selective dehydrocoupling of aromatic amines into tunable C[double bond, length as m-dash]N coupled imines or C–N coupled secondary amines, respectively, under visible light irradiation. The presence of the RuS2 or Cu2S cocatalyst not only facilitates the charge carrier separation and migration owing to the well-matched energy band structure, but also maneuvers the interfacial charge transfer routes for the selectivity switching between C[double bond, length as m-dash]N and C–N product formation. This work would inspire the rational design of ingenious semiconductor-based composites toward selective modulation in heterogeneous photocatalytic organic synthesis.
