Alkyl iodides and benzoyl peroxides provide a new general method of homolytic alkylation of protonated heteroaromatic bases. Yields are good and the substitution is selective in the positions ortho and para to the heteroatom.

A protocol for direct C-H alkylation of heteroarenes was developed using photoredox catalysis as a mode of activation for unactivated bromoalkanes. Dimeric Au(I) complex, [Au2(dppm)2]Cl2, served as an efficient photocatalyst for this transformation.
