Three new ways to synthesize 1,3-azole derivatives by microwaves

Three new ways to synthesize 1,3-azoles derivatives on mineral supports using Ca(OCl)2/Al2O3 or MnO2/SiO2 or by fusion 'in dry media' are described. The reactions are activated under microwave irradiation in a monomode Synthewave 402 reactor. The reaction times are considerably shortened and the products are obtained in higher yields and better purity, than compared to conventional heating.
