Persulphate Oxidation of Carboxylic and Sulphonic Acids and Amides.
Abstract
Structures, including stereochemistry, have been assigned to the dimeric compounds formed in the persulphate oxidation of 2-biphenylyoxyacetic acid and 2-(1-naphthyl) phenoxyacetic acid. The final aromatization step in the formation of pyrans from 2-aryloxyacetic acids is effected by persulphate anions. 2-(Biphenylylthio) acetic acids behave like the oxygen analogues on oxidation and give theipyrans and dimers, but concurrent open-chain reactions lead to disulphide formation. The corresponding sulphonylacetic acid cyclises similarly to a thiopyran dioxide but in lower yield. (Author)
