Microwave-Assisted Chemoselective Regeneration of Carbonyl Compounds from Oximes by Silica Chromate/WET SiO₂ Under Solvent-Free Conditions

Abstract

The regeneration of carbonyl compounds from oximes were performed by using silica chromate and wet SiO ₂ (w/w 50%) under microwave irradiation and solvent-free conditions with excellent yields.

Keywords:

• Carbonyl compound
• microwave irradiation
• oxime
• silica chromate
• solvent-free

Notes

^a Wet SiO₂: substrate (0.5 g: 1 mmol).

^b Isolated yields.

^c Products were characterized by m.p.s., the corresponding of 2,4-dinitrophenylhydrazone derivatives, and their IR and ¹H NMR spectra.

^d m.p. of semicarbazone derivatives.

^e m.p. of phenylhydrazone derivatives.
