Abstract
Ketoximes formed from ketones in the presence of hydroxylamine and silica gel in formic acid undergo in situ the Beckmann rearrangement under mild conditions affording in high yields the corresponding amides. Unsymmetrical aromatic ketones, methyl aryl ketones, and methyl cyclohexyl ketone under these conditions form as a rule amides mixtures.
