A catalytic protocol for synthesis of thioesters from aryl, vinyl, and benzyl bromides as well as benzyl chlorides was developed using only stoichiometric amounts of carbon monoxide, produced from a solid CO precursor inside a two-chamber system. As a catalytic system, the combination of bis(benzonitrile) palladium(II) chloride and Xantphos furnished the highest yields of the desired compounds, along

by C–S cleavage is reported. These reactions are promoted by a commercially-available, user-friendly, inexpensive, air- and moisture-stable nickel precatalyst. The process occurs with broad functional group tolerance, including free anilines, cyanides, ketones, halides and aryl esters, to efficiently generate thioethers using ubiquitous carboxylic acids as ultimate cross-coupling precursors (cf. conventional
Herein, a practical and effective synthesis of thioesters from readily available carboxylic acids and odorless disulfides was developed under photocatalytic conditions. This approach involves phosphoranyl radical-mediated fragmentation to generate acyl radicals and allows for incorporation of both S atoms of the disulfides into the desired products. In addition to batch reactions, a continuous-flow

A novel palladium-catalyzed convenientsynthesis of thioesters from various carboxylic acids and disulfides has been developed. Both aryl and alkyl carboxylic acids are capable of coupling with diaryl or dialkyl disulfides to afford the desirable thioesters in moderate to good yields. This methodology features easy accessibility of starting materials and a broad substrate scope, providing a practical

A novel nickel-catalyzed practical and simple synthesis of thioesters fromamides and disulfides has been developed. Diverse substituted aromatic amides are capable of coupling with diaryl or dialkyl disulfides via C−N/S−S cleavage to produce the desirable thioesters in moderate to good yields. This procedure features cheap metals, novel and easily preparative substrates, providing a simple and practical
