Rubber peptizer SS preparation method

The invention provides a rubber peptizer SS preparation method. The rubber peptizer SS preparation method includes the steps of subjecting benzothiazole and sodium hydroxide to high-temperature decomposition reaction so as to prepare a sodium aminothiophenol solution; dropwise adding a mixed acid solution prepared from water, sulfuric acid and hydrogen peroxide into the sodium aminothiophenol solution at 35-40 DEG C prior to oxidation reaction, and filtering to obtain DS (2,2'-diphenylamine disulphide) after the oxidation reaction is completed; adding the DS and the water into a reaction kettle, adding sodium carbonate, stirring to increase the temperature to 90-95 DEG C, dropwise adding benzoyl chloride for acylation reaction, cooling after the reaction is completed, performing solid-liquid separation and alcohol washing, and drying at 50 DEG C so as to obtain the SS (2,2'-dibenzoyl diphenyl disulfide). The rubber peptizer SS preparation method has the advantages that the raw materials are free of toxicity, cheap and easily available, and a technological process is simple and easy to operate; toxic solvents are unused, and accordingly a preparation workshop is low in toxicity and less polluted; high yield and high quality are achieved, so that the rubber peptizer SS is promising in market prospect; since the alcohol solvents can be recycled, overall cost is low and rubber peptizer SS purity can be above 98%.

Iridium-catalyzed enantioselective allylation of sodium 2-aminobenzenethiolate: An access to chiral benzo-fused N,S-heterocycles

The use of sodium 2-aminobenzenethiolate in the enantioselective iridium catalyzed allylic substitution with a range of methyl allyl carbonates allows the concise synthesis of the branch-type products with both excellent regio- and enantioselectivities, which are functionalized N,S-containing allylic intermediates for the formation of chiral benzo-fused N,S-heterocycles.
