چکیده
|
An improved and efficient method for the synthesis of 1- & 5-substituted 1h- tetrazole derivatives was described in the presence of nano-ordered mcm-41-s0₃h 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, provides a wide range of 1h-tetrazoles in good to excellent yields. the catalyst was reused five times without significant loss of catalytic activity.
