An eco-friendly system for oximation of organic carbonyl compounds under microwave irradiation

The oximation of a variety of organic carbonyl compounds was efficiently carried out with NH2OH?HCl under microwave irradiation. The reactions were performed in water or water-ethanol as green solvents to give Z-aldoxime isomers from the corresponding aldehydes and E-ketoxime isomers from the corresponding ketones in a perfect selectively with excellent yields.

NH2OH.HCl/BaCl2: A convenient system for synthesis of oximes from the corresponding of organic carbonyl compounds

A variety of aldehydes and ketones were converted to their corresponding oximes NH2OH·HCl/BaCl2 system in reflux conditions.

Synthesis of oximes with NH2OH.HCl/DOWEX(R)50WX4 system

The oximation of a variety of carbonyl compounds was efficiently carried out with DOWEX(R)50WX4/NH2OH·HCl system. The reactions were performed in ethanol to give Z-aldoximation isomers of aldehydes and E-oximaton of acetophenone derivatives in a perfect selectively. The oximation of compounds with two carbonyl groups was carried out selectively on one carbonyl moiety. Also, the oximation of aldehydes over ketones has been accomplished successfully by this system.
