The condensation of aldehydes and ketones with hydroxylamine hydrochloride gives oximes in 81-95 % yields in water and EtOH under ultrasound irradiation. Compared to conventional methods, the main advantages of the present procedure are milder reaction conditions, shorter reaction times and higher yields.
Keywords : Condensation; oxime; ultrasonication; aldehydes; ketones.
