Hypervalent iodine-mediated formation of S–S, C–S, C–O, and C–N bonds

In situ generation of acyloxyphosphoniums for mild and efficient synthesis of thioesters

“…Therefore, organic chemists have developed new synthetic methods for thioester preparation, which have attracted great interest. These methods include metal-catalyzed thiocarbonylation, 4 carbene-catalyzed thioesterification of aldehydes, 5 acyl transfer, 6 oxidative coupling reaction, 7 sulfur surrogate, 8 microwave irradiation, 9 photochemistry, 10 electrochemistry, 11 and others. 12…”
