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.}, keywords = {Nano-ordered MCM-41-SO3H,1-& 5-substituted tetrazoles,Click chemistry,[2+3] cycloaddition}, url = {https://scientiairanica.sharif.edu/article_21088.html}, eprint = {https://scientiairanica.sharif.edu/article_21088_34db3ad3693a3c5c262f61e9e6f07936.pdf} }
