Herein reported is a nickel-catalyzed reductive aryl thiocarbonylation of alkene via thioester group transfer strategy by using simple and readily available thioesters. In contrast to traditional activation of weaker C(acyl)-S bond, the C(acyl)-C bond of

Thiol and selenol esters were synthesized by a direct oxidative coupling reaction of aldehydes with disulfides or diselenides in ethyl acetate under metal-free conditions. Among the oxidants examined, tert-butyl peroxide (TBP) was shown to give the best results. For the substrates with both electron-donating and electron-withdrawing substituents, the reaction proceeded smoothly and gave moderate to good yields. Compared with the previous method, the present route is very simple, atom-economical and environmentally friendly. This journal is the Partner Organisations 2014.

Peroxymonosulfate ion, HSO5-, as OXONE, in aqueous MeCN readily converts aryl thiobenzoates, XC6H4CO*SC6H4Z (X = p-OMe, p-Me, H, p-Cl, p-CN; Z = p-OMe, p-Me, H, m-OMe, p-Cl, m-Cl, p-NO2) into carboxylic and sulfonic acids.Reactions are second order and have small substituent effects, with ρ ca. -0.6 based on ?m and ?p substituent parameters, but rates increase markedly with increasing water content in aqueous MeCN and entropies of activation are negative.The initial step is very similar to the oxidation of methyl aryl sulfides by HSO5- which has similar solvent and substituent effects.Enthalpies of activation are much lower for oxidation of the sulfides than of the corresponding esters but entropies of activation are similar.
