Radical intermediates are key species in many chemical transformations. Recent advances have provided a new suite of selective radical alkylation reactions. This Comment highlights pioneering studies using alkyl amines that act as radical precursors in a number of catalytic processes by their conversion to alkylpyridinium salts.
