A scalable reduction of sulfoxides to sulfides in a sustainable way remains an unmet challenge. This report discloses an electrochemical reduction of sulfoxides on a large scale (>10 g) under mild reaction conditions. Sulfoxides are activated using a substoichiometric amount of the Lewis acid AlCl3, which could be regeneratedviaa combination of inexpensive aluminum anode with chloride anion. This deoxygenation process features a broad substrate scope, including acid-labile substrates and drug molecules.

A conceptually intuitive synthesis of oxothioacetals is reported starting from thiosulfonates as electrophilic sulfur donors. The installation of a reactive CH2Cl motif with a homologating carbenoid reagent, followed by the immediate nucleophilic displacement with alcoholic groups [(hetero)-aromatic, aliphatic] offer a convenient access to the title compounds. Genuine chemoselectivity is uniformly observed in the case of multi-functionalized systems. (Figure presented.).

The invention belongs to the technical field of sulfur-containing organic synthesis, discloses a thioether compound and its synthetic method and application. The vinyl ether compound is acetone, b of sulfur compounds, inorganic alkali and 18 - crown ether - 6 mixing, heating and stirring, in the inorganic alkali under the action of the catalyst, the reaction under air atmosphere, and then concentrated, purified made, the vinyl ether compound of molecular formula as formula (1) as shown: Wherein R1 And R2 Selected from hydrogen atom, alkyl, alkoxy, nitro, amino, hydroxy, halogen base, acyl, aryl or a heterocyclic group. The method can avoid the toxicity is relatively large of the methylene chloride and halogenated hydrocarbon such as methylene diiodide. The synthesis step is simple, convenient and easy operation, environment friendly and under a comparatively mild condition, have high conversion, the yield of the product can be as high as 96%. The thioether compound can be applied to the production of organic synthetic intermediates in the field. (by machine translation)
