N-Benzyl and N-methyl groups migrate to the methinecarbon atom on thermolysis of pyridiniumanhydrobases. Cross-over experiments indicate an intermolecular reaction, probably involving homolysis.

Carbon disulphide and methyl iodide converted the anhydrobases (3) into 8-[(methylthio)thiocarbonyl]pyridinium iodides (4) which afforded new pyridiniumanhydrobases (5) with ethoxide. These anhydrobasesrearranged into the isomeric ketene S,S-dithioacetals (6), precursors for disulphides.
