A straightforward and convenient route has been developed for the synthesis of 3‐unsubstituted phthalide derivatives from aryl amides and paraformaldehyde by ruthenium(II)‐catalyzed C–H activation. The reaction proceeds through tandem ortho‐hydroxymethylation of aryl amide and subsequent intramolecular lactonization.
