Nanolayered cobalt–molybdenum sulphide (Co–Mo–S) materials have been established as excellent catalysts for C–S bond construction. These catalysts allow for the preparation of a broad range of thioethers in good to excellent yields from structurally diverse thiols and readily available primary as well as secondary alcohols. Chemoselectivity in the presence of sensitive groups such as double bonds,

An efficient and selective approach to the synthesis of selenide ethers containing one or two geminal C–Se bonds from readily available diselenides and phenylacetic acids was developed. Compounds containing one C–Se bond were prepared by employing air as the oxidant under metal-free conditions, whereas compounds having two geminal C–Se bonds were formed via the iron(III) chloride/oxygen/cesium carbonate
已开发出一种有效的,选择性的方法,可以从容易获得的二硒化物和苯乙酸合成含一个或两个双键C-Se键的硒醚。通过在无金属条件下将空气用作氧化剂来制备包含一个C-Se键的化合物,而通过氯化铁(III)/氧/碳酸铯(FeCl 3 / O 2)形成具有两个双键C-Se键的化合物。/ Cs 2 CO 3)系统。此外,在标准反应条件下,1,2-二苯基二硫烷也可以平稳地转化为相应的硫醚产物。

An efficient and novel method for the thioetherification of an alcohol with disulfides or NaSHundermicrowaveirradiation is presented. In the presence of iodine, a variety of alcohols were smoothly S‐alkylated with disulfides or NaSH to give the corresponding thioethers in moderate to excellent yields.

transition-metal-free decarboxylative thiolation protocol is reported in which primary, secondary, tertiary (hetero)arylacetates and α-CN substitutedacetates undergo the decarboxylative thiolation smoothly, to deliver a variety of functionalized aryl alkyl sulfides in moderate to excellent yields. Aryl diselenides are also amenable substrates for construction of C–Se bonds under the simple and mild reaction
