In this study a straightforward and efficient approach concerning synthesis of 1,3-diazole derivatives under ultrasound (US) irradiation as well as under conventional thermal heating (TH) is presented. N-alkylation under US irradiation may be considered environmentally friendly in terms of higher yields, smaller amounts of solvent used and an overall energy efficiency due to a substantial reduction of reaction times. A comparative study of ultrasound vs. conventional conditions has been performed. Overall, the use of US proved to be more efficient than TH. A possible explanation concerning the different behavior of imidazole and benzimidazole in the N1-alkylation reactions under US irradiation was proposed.

Fourteen N-azolylpropanamides have been prepared by Michael addition of azoles on acrylamide.The compounds have been fully characterized by IR and by 1H and 13C-NMR.The isolated componds are the most stable derivatives; kinetic compounds were observed but could not be isolated.
