While charge-transfer complexes involving halogen-bonding interactions have emerged as an alternative strategy for the photogeneration of carbon radicals, examples using (fluoro)alkyl bromides are limited. This report describes a dual catalytic approach radical generation from α-bromodifluoroesters and amides under visible-light irradiation. Mechanistic studies suggest that reaction proceeds through in situ bromide displacement iodide salt, generating C–I bond can be engaged by our photocatalysis platform.
