The propensity of several reagents to oxidize selenides to selenones has been evaluated; the scope and limitations of the methods are presented.
已经评估了几种试剂将硒化物氧化为硒酮的倾向;介绍了方法的范围和局限性。

Manganese is a cheap and environmentally friendly metal on Earth. Herein, we report a manganese-promoted reductive cross-coupling using easily available and odorless disulfides as thiolating agents in an excellent 100% sulfur atom economy. The protocol featured a broad substrate scope, including various alkyl disulfides and excellent functional group compatibility, constructing diverse thioethers under

derivatives react as Michael acceptors in the Corey-Chaykovsky reaction with alkylphenylselenones and alkyl diphenyl sulfonium salts. Mechanistic studies reveal that sterically demanding substituents at the carbanionic center favor formation of cyclopropanes and suppress competitive β-elimination to the alkylated products. The transformation, demonstrated also on heterocyclic nitroquinoline and nitroindazolines

Selenones are prepared by oxidation of selenides by hydrogen peroxide-benzeneseleninic acid. They react with α, β -unsaturated esters and alkylidene malonates in the presence of t-BuOK and produce alkyl Cyclopropanecarboxylates.
