Benzo-1,4-oxathiins and benzo-1,4-dithiins from 4,5-disubstituted 1,2,3-thiadiazoles

4-Aryl(or heteroaryl)-5-heterosubstituted 1,2,3-thiadiazoles on heating in the presence of sodium hydride undergo ring opening with nitrogen elimination followed by recyclization to form the corresponding 1,4-benzoxathiins and 1,4-benzodithiins.
