Palladium-Catalyzed Thiocarbonylation of Benzyl Chlorides with Sulfonyl Chlorides for the Synthesis of Arylacetyl Thioesters

A convenient procedure for the synthesis of thioesters has been developed via a palladium-catalyzed thiocarbonylation of benzyl chlorides with sulfonyl chlorides. Various arylacetyl thioesters were produced in good yields by using sulfonyl chlorides as an odorless sulfur source. Furthermore, W(CO)6 exhibited dual roles as both a solid CO surrogate and reductant here. (Figure presented.).

Method for preparing thioester compounds through carbonylation

The invention discloses a method for preparing thioester compounds through carbonylation, wherein the method comprises the following steps: adding palladium acetate, 4,5-bis(diphenylphosphine)-9,9-dimethyl xanthene, tungsten carbonyl, triethylamine, water, a benzyl chloride compound and sulfonyl chloride into an organic solvent, collecting, reacting at the temperature of 100 DEG C for 24 hours, and after the reaction is completed, performing post-treatment to obtain the thioester compounds. The preparation method is simple to operate, the initial raw materials of the reaction are cheap and easy to obtain, sulfonyl chloride is used as a sulfur source, and a thiol compound with unpleasant smell can be prevented from being used. The substrate is high in designability, the tolerance range of functional groups of the substrate is wide, and the reaction efficiency is high. Tungsten carbonyl can be used as a carbonyl source and a reducing agent, and an additional reducing agent is not needed. Various thioester compounds can be synthesized according to actual requirements, so that the practicability of the method is widened while the operation is convenient.

Air-Tolerant Direct Thiol Esterification with Carboxylic Acids Using Hydrosilane via Simple Inorganic Base Catalysis

Direct thioesterification of carboxylic acids with thiols using nontoxic activation agents is highly desirable. Herein, an efficient and practical protocol using safe and inexpensive industrial waste polymethylhydrosiloxane as the activation agent and K3PO4 with 18-crown-6 as a catalyst is described. Various functional groups on carboxylic acid and thiol substituents can be tolerated by the present system to afford thioesters in yields of 19-100%.
