Conversion of imino-1,2,3-dithiazoles into 2-cyanobenzothiazoles, cyanoimidoyl chlorides and diatomic sulfur
Autor: Oleg A. Rakitin, Charles W. Rees, O. G. Vlasova, Russell F. English
Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :201-206
Primary aromatic amines condense with 4,5-dichloro-1,2,3-dithiazolium chloride 1 to give high yields of the N-aryl imines 2 which on heating give 2-cyanobenzothiazoles 3, thus providing a simple two-step route to these heterocycles from the appropria

Direct synthesis of 2-cyanobenzimidazoles and the generation of S2
Autor: Oleg A. Rakitin, O. G. Vlasova, Charles W. Rees
Publikováno v: Tetrahedron Letters. 37:4589-4592
2-Cyanobenzimidazoles 6 are readily prepared from 1,2-diaminobenzenes 4 and 4,5-dichloro-1,2,3-dithiazolium chloride 1, either directly or through thermal or acid-catalysed rearrangement of the isolated imine intermediates 5; thermolysis of the imine

ChemInform Abstract: 2-Sulfiliminopyridines and Their Oxidation to 2-Nitropyridines
Autor: I. F. Falyakhov, Oleg A. Rakitin, O. G. Vlasova, T. N. Sobachkina, Lenor I. Khmel’nitskii
Publikováno v: ChemInform. 23
Sulfilimines of the pyridine series with electron-acceptor substituents in the ring were synthesized. It was shown that their oxidation with trifluoroperacetic acid results in the corresponding nitropyridines. The limitations of the methods were indi

ChemInform Abstract: 1,2,4-Thiadiazole 4-Oxides
Autor: O. G. Vlasova, Oleg A. Rakitin, Charles W. Rees
Publikováno v: ChemInform. 27
The first N-oxides of the 1,2,4-thiadiazole ring system are prepared by condensation of benzamidoximes with 4,5-dichloro-1,2,3-dithiazolium chloride 1; they are shown by 15N-labelling to be 4-oxides and a mechanism is proposed for their formation.
