✦ Synopsis

Synthesis of Oximes, Conversion to Nitrile Oxides and Their Subsequent 1,3-Dipolar Cycloaddition Reactions under Microwave Irradiation and Solvent-Free Reaction Conditions.

-Aldoximes and ketoximes (II) are readily synthesized from aldehydes and ketones (I) on Al 2 O 3 under microwave irradiation. At higher irradiation power, aldoximes hydrate to nitriles and ketoximes rearrange to amides. Aldoxime (IIa) can be transformed into isoxazoline (IV) or isoxazoles (VI) and (VII). -(TOUAUX,

Aldoximes and ketoximes were readily synthesized from aldehydes and hydroxylamine hydrochloride on Al 2 O 3 without solvent under microwave irradiation. At higher irradiation power, aldoximes dehydrated to nitriles and ketoximes rearranged to amides. Aldoximes reacted in a one-pot reaction with Nchl
