In previous papers we showed that oxidation of thioketones (2,3) and dithiocarboxylic esters (4) with peracid represents a facile method for the conversion of the >C=S group in these molecules into the >C=S=O moiety. Although

โฆ Synopsis
While cyclic sulfonic acid esters, sultones, have been studied extensively3, the cyclic esters of the lower oxidation state sulfur acids, sulfinate esters, have remained relatively unknown.
To date, only six alicyclic sulfinate esters have been reported 4.
