A method for synthesis of aryl thioether compound

The invention discloses a synthetic method of an aryl thioether compound as shown in a formula (3). The polysubstituted aryl thioether compound is obtained by using aryl iodide or an aryl trifluoromethane sulphonate derivative and halogenated hydrocarbon as reaction raw materials and Na2S2O3 as a vulcanization reagent and reacting in a reaction solvent under the effect of a metal palladium catalyst. The synthetic method is mild in reaction conditions, simple in reaction operation and relatively high in productivity, can provide key skeleton structures for synthesis of lots of natural products and medicines and can be widely applied to industrialization scale production.

Direct cross-coupling access to diverse aromatic sulfide: Palladium-catalyzed double C-S bond construction using Na2S 2O3 as a sulfurating reagent

The Pd-catalyzed cross-coupling of aryl halides, alkyl halides, and Na 2S2O3·5H2O to deliver aromatic thioethers is described. Pyridine, furan, thiophene, benzofuran, benzoxazole, benzothiophene, benzothiazole, and pyrazine are all amenable to this protocol. The odorless and stable solid Na2S2O 3·5H2O was used as a convenient and environmentally friendly source of sulfur. Pd-catalyzed cross-couplings without thiols or thiophenols to build C-S bonds have not previously been achieved, which renders our observation more striking.

Alkyl- and arylthiolation of aryl halides catalyzed by fluorinated bis-imino-nickel NNN pincer complexes [NiCl2{C5H 3N-2,6-(CHNArf)2}]

The synthesis of bis-imino nickel(II) NNN pincer complexes of the type [NiCl2{C5H3N-2,6-(CHNArf) 2}]; Arf= C6H3-2,3-F2 (1), C6H3-2,5-F2 (2), C6H 3-3,4-F2 (3), C6H3-3,5-F2 (4), C6H2-2,3,4-F3 (5), C6H 2-2,3,6-F3 (6), C6H2-2,4,5-F 3 (7), C6H2-2,4,6-F3 (8), has been achieved and their reactivity in alkyl- and arylthiolation reactions of halobenzenes examined. The use of fluorinated substituents Arf on the imines has allowed the tuning of the electronics in these complexes and the influence of these substituents and those of the disulfides in the thiolation reactions have been analyzed.
