NH2OH.HCl/BaCl2: A convenient system for synthesis of oximes from the corresponding of organic carbonyl compounds
Talaei, Farhad,Setamdideh, Davood
, p. 1583 - 1587 (2016/08/06)
A variety of aldehydes and ketones were converted to their corresponding oximes NH2OH·HCl/BaCl2 system in reflux conditions.
An eco-friendly system for oximation of organic carbonyl compounds under microwave irradiation
Batmani, Hana,Setamdideh, Davood
, p. 699 - 703 (2015/01/16)
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.
Synthesis of oximes with NH2OH.HCl/DOWEX(R)50WX4 system
Setamdideh, Davood,Khezri, Behrooz,Esmaeilzadeh, Seyran
, p. 1119 - 1124 (2012/10/30)
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.
Novel oxidative nitrogen to carbon rearrangement found in the conversion of anilines to benzaldoximes by treating with HCHO/H2O2

, p. 2886 - 2890 (2008/09/21)
Novel rearrangement was found by reacting anilines with HCHO/H2O2 resulting in the synthesis of various benzaldoximes. The mechanism of the rearrangement is proposed and suggested that the rearrangement might proceed via unstable N-phenyloxazirane intermediate followed by the transfer of aryl moiety from nitrogen to carbon atom leading to the formation of benzaldoxime.
P2O5/SiO2 as an efficient reagent for the preparation of Z-aldoximes under solvent-free conditions
Eshghi, Hossein,Gordi, Zinat
, p. 1553 - 1557 (2007/10/03)
A facile and efficient method for the preparation of Z-aldoximes is improved by means of P2O5/SiO2 reagent in solvent-free media. Advantages of this method are the use of inexpensive and selective reagent, with high yields in simple operation, and short reaction time under solvent-free conditions.
