Abstract

Abstract Dithiocarboxylation of some halogenated pyridine sulphones with carbon disulphide and sodium hydride leads to the formation of thiomethyl derivatives via Smiles rearrangement of the initially produced dianion, fragmentation and subsequent methylation. In one instance the pyridino [2, 3-b]-1, 4-dithiine 7 was obtained. The thioether 2d was also converted into a thiomethyl derivative when subjected to the same reaction sequence.
