A new synthetic approach for the preparation of alkenyl-1,2,4-triazole derivatives based on microwave-induced C–C cross-coupling Heck reactions is described. To the best of our knowledge, this is the first application of the Heck reaction to a dihalogenated 1,2,4-triazole. This approach allows the introduction of a wide range of equivalent or different alkenyl substituents in the 5- and/or 3-positions, thus extending the possibilities for the preparation of these valuable derivatives. A similar microwave-induced synthetic procedure has also been applied to the Heck reaction of 4-vinyl-1,2,3-triazoles.
