Abstract
An efficient and fast procedure for the synthesis of 2-(2-pyridyl)azoles is described using ionic liquids as catalysts under microwave irradiation. The X-ray crystallographic analyses for three of the four synthesized compounds are presented. Potentiodynamic polarization studies were carried out to analyze the electrochemical behavior of the compounds in corrosive acidic media. Of the four derivatives, one compound was detected to be an effective corrosion inhibitor prototype for oil refinery environments.
