DOI: 10.1002/aenm.202500332

Abstract: Manipulating the central cores of non‐fullerene acceptors is crucial for enhancing the performance of organic solar cells (OSCs). While recent Y‐acceptors have leveraged a two‐dimensional (2D) π‐expansion strategy to incorporate symmetric fused‐pyrazine central cores, challenges… read more here.

DOI: 10.1002/ejoc.201700297

Abstract: An extensive study of the chemoselective Pd-catalyzed inter- and intramolecular direct C–H arylation of N-benzylated 5-carboxyimidazoles with halides with and without CuI assistance in 1,4-dioxane as a low-polarity solvent was explored. The method was suitable… read more here.

DOI: 10.1002/ejoc.202400575

Abstract: Herein, we report an efficient route for coumarin C3‐C4 fused imidazole scaffolds via indium chloride‐mediated single‐step transformation of 4‐azido‐coumarin with amines/aldehydes and coumarin C3‐C4 fused 5‐substituted‐1,4‐benzodiazepine scaffolds with 1,2‐azide‐nitrogen migration through two‐step sequential synthesis via the transitory intermediacy… read more here.
