✦ Synopsis
The oxidation of phenol with dioxygen in the presence of copper metal, primary alcohols and pyridine, under mild conditions, produces new compounds deriving from the aromatic ring contraction (alkyl I-hydroxy-2-oxo-4,.5,5-trialkoxycyclopent-3-ene-I-carboxylate 2) which were characterized by 'H and13C-NMR. In particular an X-ray study of the methyl derivative is reported.
