Organocatalyzed Photoelectrochemical C−H Amination of Arenes

, 2021
Catalytic C–H/N–H cross-coupling is considered an ideal strategy for accessing anilines and derivatives, but its synthetic execution remains extremely challenging, especially when the exclusion of external oxidants is desired.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites

Advanced Functional Materials, EarlyView.
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...
