N-vinyl-2-pyrrolidone → 1-Phenyl-1H-1,2,3-triazole

Participants

Reaction Steps

In the method of preparation, the reaction between the N-vinylpyrrolidinone and the phenyl azide is carried out at room temperature in ethanol as solvent, and allowed to stand in the dark for several weeks, depending on the reactivity of the phenyl azides. Refluxing the reaction mixture eliminates the 5-(2-oxo-1-pyrrolidino) group and yields the 1-phenyl triazole.
