An iron-catalyzed coupling reaction of methylarenes with thiols leading to thioesters has been developed. The reactions were carried out in water with tert-butyl hydroperoxide (TBHP) as the oxidant and polyoxyethanyl α-tocopheryl sebacate (PTS) as the surfactant. The reaction medium is compatible with a series of functional groups and can be reused.

A metal‐ and oxidant‐free catalytic method for accessing structurally diverse thioesters from readily accessible, widespread aldehydes, is described. A strategy of a simple organic 9,10‐phenanthrenequinone‐promoted hydrogen atom transfer (HAT) with visible light was successfully implemented to selectively generate acyl radicals without inducing crossover reactivity of thioester products. The preparative

Novel CDC approaches for the synthesis of thioesters and thioethers was developed via sp3 C–H activation of methylarenes and subsequent functionalization.
A rhodium complex catalyzed the reaction of aryl methylethers and thioesters giving the corresponding aryl esters and methyl sulfides. S-(p-Chlorophenyl) p-(dimethylamino)benzothioate was used for the reaction of methyl aryl ethers with electron-withdrawing groups, and an S-(p-tolyl) derivative was used for those with electron-donating groups. Polymethoxybenzenes were converted to the esters in a

A new catalytic protocol for the synthesis of selenoesters from aryl iodides and diaryl diselenides has been developed, where formic acid was employed as an efficient, low-cost, and safe substitute for toxic and gaseous CO. This protocol presents a high functional group tolerance, providing access to a large family of selenoesters in high yields (up to 97%) while operating under mild reaction conditions
已经开发了一种用于从芳基碘化物和二芳基二硒化物合成硒代酯的新催化方案,其中甲酸被用作有毒和气态 CO 的有效、低成本和安全的替代品。该协议具有高官能团耐受性,在温和的反应条件下以高产率(高达 97%)获得一大类硒代酯,避免使用难以操作、易氧化且气味难闻的硒醇。此外,通过首次使用二有机基二硫化物作为前体,该方法可以有效地扩展到具有中等至优异产率的硫酯的合成。
