Palladium- and Nickel-Catalyzed Decarbonylative C–S Coupling to Convert Thioesters to Thioethers
摘要:
This Letter describes the development of a catalytic decarbonylative C-S coupling reaction that transforms thioesters into thioethers. Both Pd- and Ni-based catalysts are developed and applied to the construction of diaryl, aryl alkyl, and heterocycle-containing thioethers.

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

used an electrochemical reduction method to obtain thiyl radicals from sulfinicacids. In a simple undivided cell, various acyl chlorides and sulfinicacids were compatible, generating 40 examples of the desired thioesters in up to 95% yields. Preliminary mechanism studies suggested that the formation of thiyl radicalspecies from sulfinicacid proceeded via multiple steps of a single electron transfer
C-S键的构建是合成化学、药物化学和材料化学中的一个重要过程。硫醇通常用作提供 S 源的起始材料。然而,它们难闻的气味和毒性促使我们寻找替代品。在这种情况下,我们使用电化学还原方法从亚磺酸中获得硫自由基。在一个简单的未分裂池中,各种酰氯和亚磺酸是相容的,以高达 95% 的产率生成 40 个所需硫酯的例子。初步机制研究表明,亚磺酸形成硫自由基物质是通过单个电子转移过程的多个步骤进行的。

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

Trihexyl(tetradecyl)phosphonium hexafluorophosphate, a phosphonium salt ionic liquid (PSIL) is a particularly effective general reaction media for the Pd-catalyzed carbonylation reaction of iodoarenes and thiols to form thioesters. Recycling of the ionic liquid containing active Pd-catalyst was also demonstrated.
