Thermal conversion of a pyridine-bridged bisdithiazolyl radical to a zwitterionic bisdithiazolopyridone

Chem Commun (Camb). 2010 Jul 7;46(25):4496-8. doi: 10.1039/c0cc00775g. Epub 2010 May 20.

Abstract

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.
