Abstract
A process for producing an amide which comprises subjecting an oxime to liquid phase rearrangement in the presence of phosphorus pentoxide and at least one compound selected from the group consisting of N,N-dialkyl amides, N-alkyl cyclic amides and dialkyl sulfoxides and optionally a fluorine-containing strong said or its derivative. Said process can rearrange an oxime to a corresponding amide in a good yield under mild reaction conditions in the presence of a less stoichiometric amount of a catalyst.
