Abstract
A third reaction center in the phenoxazinone molecule, viz., the 9 position in the benzenoid ring, was observed for the first time in the reaction of 3-phenoxazinone and its 2-hydroxy and 2-ethoxy derivatives with p-thiocresol. In conformity with this, 2,7,9-triarylthio derivatives are formed along with the usual 2,7-disubstituted derivatives of 3-phenoxazinone. The structures of the compounds obtained were confirmed by the PMR and EPR spectra and a number of chemical transformations.
