Abstrakt:	The reactions of isomeric tetrafluoropyridines and pentafluoropyridine with sodium N,N-dimethyldithiocarbamate were studied. Substantial differences were found between the nature of their chemical transformations and those of the chlorine analogs. It was shown that tetrafluorocyanopyridines do not undergo heterocyclization with sodium N,N-dimethyldithiocarbarnate to form derivatives of 1,3-dithiolo[4,5-c]pyridine. Instead, extrusion of the CS2 molecule from the N,N-dimethyldithiocarbanuue substituent at position 2 of the pyridine ring occurs.
