Photoexcited Copper-Catalyzed Atom Transfer Radical Addition (ATRA) Reaction of Unsaturated C–C Bonds with 1-Iodo- o -carboranes

In photoinduced, radical-mediated carbon-terminus carborane functionalization, critical constraints include intricate substrate precursor synthesis, the requirement for ultraviolet light, and costly photosensitizers. This study employs cost-effective and readily available copper complexes as photocatalysts, enabling the successful atom transfer radical addition (ATRA) reactions between iodocarboranes and unsaturated bonds. Using this catalytic system, a series of structurally unique carborane-containing iodinated compounds and AIE-active molecules have been efficiently constructed.
