Reactions of polyhalogenopyridines. 15. Reaction of isomeric tetrachlorocyanopyridines and pentachloropyridine with potassium isopropyltrithiocarbonate
Abstract
The reaction of isomeric tetrachlorocyanopyridines and pentachloropyridine with potassium isopropyltrithiocarbonate was investigated. It was found that the structure and composition of the reaction products depend both on the initial polychloropyridines and on the solvent in which the process is carried out. The intramolecular transformations of the isopropyltrithiocarbonate derivatives of tetrachloro-2-cyanopyridine in acetonitrile solution lead to 1,3-dithiolo[4,5-c]pyridines. In other cases heterocyclization was not observed. If the reactions were conducted in ethanol (except with tetrachloro-3-cyanopyridine) thioalkylation of the pyridine ring occurred.
