The reactions were carried out in oil bath (70°C to 80°C) at solvent-free conditions to afford oximes in high to excellent yields. This method offers some advantages in terms of clean reaction conditions, recyclable of catalyst, short reaction times, easy work-up procedure, and suppression of side products.
