An improved and efficient method for the synthesis of 1- & 5-substituted 1H-tetrazole derivatives has been described in the presence of nano-ordered MCM-41-SO3H as an effective heterogeneous catalyst. This metal-free protocol, [2+3] cycloaddition of sodium azide to various nitriles or ethyl N-phenyl formimidate intermediate under mild reaction conditions, afford a wide range of 1H-tetrazoles in good to excellent yields. The catalyst was reused for five times without significant loss of catalytic activity.
