synthesis of phenoxathiinderivatives. A range of 1,2-dihaloarenes or 1-halo-2-nitroarenes reacted with 2-sulfanylphenol to give the desired products in good-to-excellent yields. It is intriguing that 1-halo-2-nitroarenes containing electron-donating groups worked well as substrates in this reaction. A simple and efficient method was developed for the synthesis of phenoxathiinderivatives. A range of

Aryl esters of 2-nitrobenzenesulphenic acid rearrange on being heated in an inert solvent in the dark, or upon being set aside in the dark at room temperature, to give the appropriately substituted hydroxyphenyl 2-nitrophenyl sulphides together with di-2-nitrophenyl disulphide. The methyl ester gives substituted phenyl 2-nitrophenyl sulphides on prolonged heating with alkyl- or alkoxybenzenes. 2-N
