REAKTIONEN VON THIOXOHETEROCYCLEN MIT N-CHLORAMIDEN II. N-SUBSTITUIERTE 2- ODER 4-THIOPYRIDONE UND NATRIUM-N-CHLORBENZOLSULFONAMIDE

N-Substituted 2- and 4-pyridinethiones A react with sodium-N-chlorobenzenesulfonamides 1 to N-phenylsulfonyl-S-pyridylidenesulfimides B, N,N'-bis(phenylsulfonyl)-S-pyridiniosulfodiimidates C and N-pyridylidenebenzenesulfonamides D.The constitution of the new pyridiniosulfodiimidates C is proved by X-ray crystal structure of one compound C and by 1H-NMR spectra of all 1-methylpyridinio-compounds C, which have a downfield shift for the N-methyl-δ-values.Formation, stabilities, IR-, 1H-NMR-spectra and bond systems of A-D are discussed.Key words: Pyridinethiones; sodium N-chlorobenzenesulfonamides; N-phenylsulfonyl-S-pyridylidenesulfimides; N,N'-bis(phenylsulfonyl)-S-pyridiniosulfodiimidates; N-pyridylidenebenzenesulfonamides; polarity of sulfur bonds.
