The Reaction of Some Halogenated Pyridine Thioethers and Sulphones with Carbon Disulphide

Article abstract of DOI:10.1002/prac.19933350309

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.
