Thermal conversion of a pyridine-bridged bisdithiazolyl radical to a zwitterionic bisdithiazolopyridone.
The methoxy-substituted bis-1,2,3-dithiazolyl radical 4a thermally decomposes to afford the zwitterionic bis-1,2,3-dithiazolopyridone 5a; EPR spectroscopic analysis indicates a rearrangement of the radical prior to loss of the methyl group.
