The development of new reusable and efficient heterogeneous catalysts for the construction of bioactive heterocyclic compounds is of great interest in the present era. Two-dimensional (2D) materials, especially 2D vanadium carbide (V2CTx MXene), are widely used in energy storage and conversion because of their good electronic properties and broad surface area, but 2D V2CTx MXene has not been explored as a catalyst support for organic transformation. Herein, we demonstrate a smooth cyclization reaction between aldehydes and hydrazides to construct 2,5-disubstituted-1,3,4-oxadiazoles catalyzed by 2D V2CTx MXenes. We were able to attach a wide range of substituents on the 2nd and 5th positions of the 1,3,4-oxadiazole ring. The present protocol showed broad functional group tolerance with product yields ranging from 84% to 93% in a shorter reaction time (30-45 min). The 2D V2CTx MXene catalyst was able to produce good yields of product even after five catalytic cycles.
