1,5-Rearrangement of enol acylates of aryl-1H-1,2,4-triazol-1-ylmethyl ketone

Article abstract of DOI:10.1007/BF00698444

The rearrangement of enol acylates of aryl 1H-1,2,4-triazol-1-ylmethyl ketones at 140-150 deg C in acetic anhydride is studied.The migration of the acyl group to the C(5) atom of the heterocycle is found to be intramolecular.The characteristics of the original and final products are presented.X-ray structural studies of the enol acetates of 2,4-dichlorophenyl 1H-1,2,4-triazol-1-ylmethyl ketone and 2,4-dichlorophenyl 5-acetyl-1H-1,2,4-triazol-1-ylmethyl ketone are carried out.
