Deep Eutectic Solvent like choline chloride/ glycerol (1:2 mol mol–1) proved to be an effective, sustainable reaction medium to easily synthesize both phenacyl azides and symmetrical 2,5-diarylpyrazines of interest in pharmacology and in coordination chemistry. Notable features of our report include: (i) nucleophilicsubstitutionreactions of α-halo carbonyl compounds to the corresponding phenacyl azides
