Abstract: We report a radical-based organocatalytic method for the direct benzylation of allylic C-H bonds. The process uses nonfunctionalized allylic substrates and readily available benzyl radical precursors and is driven by visible light. Crucial was the… read more here.

DOI: 10.1021/jacs.2c12466
Abstract: We report a photochemical method for the functionalization of pyridines with radicals derived from allylic C–H bonds. Overall, two substrates undergo C–H functionalization to form a new C(sp2)–C(sp3) bond. The chemistry harnesses the unique reactivity… read more here.

DOI: 10.1039/d2cc01638a
Abstract: Reported herein is a rare example of asymmetric catalytic functionalisation of enals at the remote γ-position, proceeding via a radical path. The process requires visible light and exploits the synergistic actions of two distinct organocatalysts.… read more here.
