Photocatalytic (Het)arylation of C(sp³)–H Bonds with Carbon Nitride

Graphitic carbon nitride materials have attracted significant interest in recent years and found applications diverse light-to-energy conversions such as artificial photosynthesis, CO2 reduction, or degradation of organic pollutants. However, their utilization synthetic photocatalysis, especially the direct functionalization C(sp3)–H bonds, remains underexplored. Herein, we report mesoporous graphitic (mpg-CN) a heterogeneous semiconductor photocatalyst for arylation bonds combination with nickel catalysis. Our protocol has broad scope (>70 examples including late-stage drugs agrochemicals), is operationally simple, shows high chemo- regioselectivities. Facile separation recycling mpg-CN catalyst its low preparation cost, innate photochemical stability, toxicity are beneficial features overcoming typical shortcomings homogeneous photocatalysis. Detailed mechanistic investigations kinetic studies indicate that an unprecedented energy-transfer process (EnT) from to complex operating.
