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.

A series of symmetrical and unsymmetricalbenzylthioethers have been synthesised using a onepot reaction frombenzylhalides and thiourea. This procedure avoids the isolation or handling of malodorous thiols and generates high yields of benzylthioethers in excellent purity.

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。
Synthesis and characterization of sulfide/sulfone-containing 18-8-18-membered-ring ladder-type siloxanes
and tricyclic 18-8-18-membered-ring ladder-type siloxane-based compound (7), with sulfide units inserted in the backbone were prepared through B(C6F5)3-catalyzed Piers–Rubinsztajn reaction. Further oxidation of 5 and 7 with m-CPBA enables the synthesis of the novel sulfonyl-containing cyclic and ladder-type compound (8 and 9) in high yields. Both tricyclic ladder-type products (7 and 9) show superior
