The organocatalytic synthesis of perfluorophenylsulfides: Via the thiolation of trimethyl(perfluorophenyl)silanes and thiosulfonates

The organic superbase t-Bu-P4-catalyzed direct thiolation of trimethyl(perfluorophenyl)silanes and thiosulfonates was developed. Yields of perfluorophenylsulfides of up to 97% under catalysis of 5 mol% t-Bu-P4 were achieved. This method was shown to provide an efficient way to construct the perfluorophenyl-sulfur bond under mild metal-free reaction conditions. This journal is

Preparation method of thiosulfonate compound

The invention belongs to the field of organic synthetic chemistry, and particularly discloses a preparation method of a thiosulfonate compound. The specific preparation process comprises the following steps: taking aryl diazonium salt, sodium pyrosulfite and thiophenol/mercaptan as raw materials, taking organic dye as a photocatalyst, adding an organic solvent, and reacting for 12 hours at room temperature under the irradiation of an LED visible light lamp and nitrogen protection to generate thiosulfonate; and after the reaction is finished, adding distilled water into the reaction system, extracting the reaction liquid with ethyl acetate, concentrating the extraction liquid to obtain a crude product, and carrying out silica gel column chromatography separation on the crude product to obtain thiosulfonate. According to the method, simple and easily available sodium pyrosulfite is used as a sulfone source, cheap organic dye is used as a photocatalyst, clean light energy is used as a reaction energy source, a high-energy-consumption heating device and a metal catalyst or strong acid are not used, the reaction condition is mild, the operation is simple and convenient, and a green synthesis strategy is provided for thiosulfonate.

Nickel-Catalyzed Defluorinative Reductive Cross-Coupling Reaction of gem-Difluoroalkenes with Thiosulfonate or Selenium Sulfonate

A nickel-catalyzed defluorinative reductive cross-coupling of gem-difluoroalkenes with thiosulfonate or selenosulfonates is described. The reaction involves the formation of thiolated or selenylated monofluoroolefins via regioselective C-F bond cleavage and C-S or C-Se bond formation and features easily available substrates, mild reaction conditions, and high E-selectivity. One of the derivatives by further cross coupling with PhMgBr exhibited an aggregation-induced emission enhancement effect.
