Copper-Catalyzed Cross-Coupling of Thiols, Alcohols, and Oxygen for the Synthesis of Esters was written by Lim, Seungyeon;Ji, Miran;Wang, Xi;Lee, Chan;Jang, Hye-Young. And the article was included in European Journal of Organic Chemistry in 2015.SDS of cas: 27249-90-7 This article mentions the following:
Copper-catalyzed, one-pot, three-component coupling reactions using thiols, alcs., and oxygen to form a variety of esters in good yields were studied. In the presence of easily oxidized benzylic and allylic alcs., thiols were selectively oxidized to form thionoesters, which underwent facile S/O exchange to afford esters. Thiols may be used as an alternative benzoyl source under mild aerobic conditions. In the experiment, the researchers used many compounds, for example, Benzyl benzodithioate (cas: 27249-90-7SDS of cas: 27249-90-7).
Benzyl benzodithioate (cas: 27249-90-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.SDS of cas: 27249-90-7
