Electron-rich aromatic aldehydes react with sodium azide in the presence of aluminum chloride in boiling tetrahydrofuran to give the corresponding nitriles in good yields, while electron-deficient or hindered aromatic aldehydes lead to (diazidomethyl)arenes in moderate yield under similar conditions.
