Lead-Free Metal Halide Double Perovskite-Photoelectrocatalyzed Activation of C(sp³)‑H Bonds and Alkylation of Alkenes and Azo Compounds.

ABSTRACT: Photoelectrocatalysis offers a powerful method for driving organic transformations by combining light and electrical energy to access more extreme potentials to generate reactive intermediates under milder conditions. Herein, we report the first application of a metal halide perovskite photoelectrocatalytic system for C-(sp³)-H activation, leading to C-C and C-N bond formation via alkylation. A lead-free, alloyed double perovskite, Cs₂Ag_0.95Na_0.05BiBr₆, was engineered as a relatively stable photoanode and used catalytically (0.5-1 mol %) under visible-light irradiation and ambient conditions with 9,10-diphenylanthracene as a cocatalyst to facilitate cross-coupling organic syntheses. Extensive characterization of the photoanode by elect
