Application of Lead-Free Metal Halide Perovskite Heterojunctions for the Carbohalogenation of C–C Multiple Bonds

Year: 2025

Type: article

Abstract: High Resolution Image Download MS PowerPoint Slide A graphitic carbon nitride/lead-free double perovskite heterojunction ( g -C 3 N 4 /Cs 2 AgBiCl 6 ) has been adopted as a heterogeneous photocatalyst under visible light irradiation. The employed material enabled the atom transfer radical addition-type carbohalogenation of multiple C–C bonds, including (internal) alkenes and alkynes, with alkyl halides. The protocol showed a remarkable functional group tolerance, compatible with the late-stage functionalization of natural and pharmaceutical derivatives, and could be easily scaled up, delivering >1 g of the desired products.
