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
