The hydrolysis of thioacetic, thiobenzoic, and three substituted thiobenzoic acids in perchloric and sulfuric acids

Autor: Sin Cheong Wong, Graeme Welch, John T. Edward

Publikováno v: Canadian Journal of Chemistry. 56:935-940

The rates of hydrolysis of thioacetic, thiobenzoic, and three substituted thiobenzoic acids increase with concentration of solvent sulfuric or perchloric acid to a maximum in 30–40% acid and then decrease. Yates–McClelland r, Bunnett–Olsen [For

The Dissociation of Anilinium Ions in Aqueous Dimethylsulfoxide

Autor: Graeme Welch, Keith Yates

Publikováno v: Canadian Journal of Chemistry. 50:474-478

The pKa values often substituted primary anilines and six substituted tertiary anilines have been determined in 70% DMSO–water. The ΔpKa values relative to those in aqueous solution indicate that DMSO is about 2 log units stronger as a base than H
