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,

N-heterocyclic carbenes can be used to substitute the highly carcinogenic aminophosphines to extrude sulfur from disulfides from thioethers (here R=aryl). Furthermore, pharmaceutically more interesting compounds such as cystine can be transformed to lanthionine.
N-杂环卡宾可用于替代高度致癌的氨基膦,以从硫醚(此处 R = 芳基)的二硫化物中挤出硫。此外,药学上更有趣的化合物如胱氨酸可以转化为羊毛硫氨酸。
