The use of PhSZnBr as sulfenylating agent in a solvent-free protocol to prepare thiol esters in excellent yields from acyl chlorides is reported. The products were efficiently obtained by grinding the neat reagents for 5 min in a mortar. DFT calculations
Method for preparing thioester compounds through carbonylation
-
Paragraph 0034-0041, (2021/06/23)
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.

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.).
An efficient synthesis of thioesters via TFA-catalyzed reaction of carboxylic acid and thiols: Remarkably facile C-S bond formation
El-Azab, Adel S.,Abdel-Aziz, Alaa A.-M.
experimental part, p. 1046 - 1055 (2012/07/17)
A general, facile, and efficient new synthetic path to thioesters was established by employing defined TFA-catalyzed reaction of carboxylic acid and thiol under mild conditions. The structure of the newly synthesized compounds was determined by infrared spectroscopy, nuclear magnetic resonance, and a single crystal X-ray crystallographic analysis.

Phenylthiolation of some carboxylic acids catalyzed by AlCl3 in the presence of excess dehydrating agent (ZnCl2) has been achieved. Moreover, regiospecificity was tested of some dioic acids and found to be specific at the aliphatic p
Silica-promoted facile synthesis of thioesters and thioethers: A highly efficient, reusable and environmentally safe solid support
Basu, Basudeb,Paul, Susmita,Nanda, Ashis K.
experimental part, p. 767 - 771 (2010/09/05)
An efficient, mild and rapid procedure for the acylation and alkylation of aromatic and aliphatic thiols mediated on a silica gel surface at room temperature is described. The protocol allows the protection of thiols under neutral heterogeneous conditions without requiring any bases or Lewis acids, and the silica gel used as the promoter can be recycled for several runs without any loss of activity.
