Transformations that selectively functionalize aliphatic C-H bonds hold significant promise to streamline complex molecule synthesis. Despite the potential for site-selective C-H functionalization, few intermolecular processes of preparative value exist. Herein, we report an approach to unactivated, aliphatic C-H bromination using readily available N-bromoamide reagents and visible light. These halogenations

The generality of light initiated halogenative decarboxylation of thiohydroxamic esters was studied. This method gave high yields of alkyl chlorides, bromides and iodides derivedfrom primary, secondary and tertiairy substituted carboxylic acids.
