Synthesis of Isothiazoles and Isoselenazoles through Rhodium-Catalyzed Oxidative Annulation with Elemental Sulfur and Selenium

A rhodium-catalyzed oxidative annulation of benzimidates with elemental sulfur for the direct construction of isothiazole rings is reported. The proposed reaction mechanism involving Rh(I)/Rh(III) redox is supported by a stoichiometric reaction of metallacycle species as well as DFT calculations. This method is also applicable to selenium cyclization to produce isoselenazole derivatives. The alkoxy substituent at C3 can be used for further functionalization of the azole core.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 35285-69-9, in my other articles.

1,2,3-Dithiazole chemistry in heterocyclic synthesis

The chemistry of various 5H-1,2,3-dithiazoles is investigated with emphasis on assisted ring opening and ring closure reactions leading to new heterocycles. Thus on treatment with catalytic tetraalkylammonium iodide N-(2-chloropyrid-3-yl)- and N-(4-chloropyrid-3-yl)-4-chloro-1,2,3-dithiazol- 5H-imines 19 and 20 give thiazolo[ 5,4-b] pyridine-2-carbonitrile 16 and thiazolo[ 4,5-c] pyridine-2-carbonitrile 17 respectively. Similar treatment of bisdithiazoles 29 and 30 afford high yielding routes to 1,3,4-thiadiazole- 2,5-dicarbonitrile 31 and thiazole-2,4,5-tricarbonitrile 32 respectively. N-(Pyrid-3-yl)-4-chloro- 1,2,3-dithiazol-5H-imine 36 reacts with secondary alkylamines to give as main product pyrido[ 2,3-d] pyrimidines 37 and several minor byproducts including a deep green quinoidal 2,2′-bithiazole 40. Dithiazolylidenacetonitriles 43 react with either anhydrous HBr or tetraalkylammonium chloride to afford a series of 3-halo-4-substituted- isothiazole-5-carbonitriles 45 and 52 respectively. The reactions of dithiazoles 43 with tetraalkylammonium chloride are complicated owing to the formation of isothiazolopentathiepin-8- carbonitrile 53, isothiazolodithiin-4,5,7-tricarbonitrile 54, tetracyanothiophene 56 and an unidentified compound 55 whose possible structures are proposed. The mechanistic rationales for the formation of the identified products are proposed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 870-50-8. Category: isothiazole.

Complexation in a 5-acylpyrimidine-4-thione-aliphatic diamine-metal(II) chloride system (M = Ni or Co). The molecular structure of fac-tris(5-acetyl-2,4-dimethylpyrimidine-6-thiolato)cobalt(III)

The reactions of 5-acylpyrimidine-4-thiones with aliphatic diamines in the presence of Ni-II and Co-II salts were studied. New Ni-II and Co-II complexes with ligands of the pyrimidinethione series were synthesized. The results of the reactions of 5-acetyl-6-methyl-2-phenylpyrimidine-4-thione and 5-acetyl-2,6-dimethylpyrimidine-4-thione with ethylenediamine or 1,3-diaminopropane in the presence of NiCl(2)(.)6H(2)O or CoCl(2)(.)6H(2)O depend on (1) the nature of the substituent at position 2 of the pyrimidine ring, (2) the length of the polymethylene bridge between the nitrogen atoms in the diamine molecule, (3) the nature of complex-forming metal, and (4) the pyrimidinethione: diamine ratio. The resulting complexes were studied by electrochemical methods. The mechanism of electrooxidation and electroreduction of 5-acylpyrimidine-2-thiones and related nickel and cobalt complexes was proposed. The structures of the complexes were investigated by NMR, UV-Vis spectroscopy, and IR spectroscopy and mass spectrometry. The molecular structure of fac-tris(5-acetyl-2,4-dimethylpyrimidine-6-thiolato)cobalt(III) was established by X-ray diffraction. According to semiempirical quantum-chemical calculations by the PM3(tm) method, both the highest occupied and lowest unoccupied molecular orbitals in the molecules of the compounds under study have a pi symmetry and are localized predominantly on the ligand fragments.

Cross-coupling reactions on azoles with two and more heteroatoms

Recent progress in the field of transition-metal-catalyzed cross-coupling reactions on various azole systems is summarized. Most important C-C- and C-X-bond formation methodologies (Negishi, Suzuki-Miyaura, Stille, Kumada-Corriu-Tamao, Hiyama, Sonogashira, Heck, C-H activation) are reviewed and discussed for the imidazole, oxazole, thiazole, pyrazole, isoxazole, and isothiazole system, as well as for azoles with more than two heteroatoms. This review covers the literature that appeared in the past ten years up to the end of 2005 with corresponding azoles used either as metal organyl or halide (including triflates and some other less frequently applied leaving groups); literature describing azole structures only as ligands was not included. ((c) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006).
