A single-step gold(I)-catalyzed chemoselective protocol to access ortho-substituted diarylsulfones has been established. Acenaphthoimidazolylidene gold complexes are effective catalysts for the arylsulfonylation of boronic acids by potassium metabisulfite (K2S2O5) and diaryliodonium salts to access (poly-)ortho-substituted diarylsulfones even in gram scale. Unlike the transition metal-catalyzed two-component coupling systems, the sterically hindered aryl groups in diaryliodonium salts are preferentially transferred over less bulky ones to form synthetically difficult targets, including those of pharmaceutical importance. This study involved multiple reactions and reactants, such as Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4Electric Literature of C17H18F3IO3S).
Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (cas: 1204518-02-4) belongs to iodide derivatives. Indole exists overwhelmingly in the 1H-indole form as do other simple indoles. They are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas.Electric Literature of C17H18F3IO3S
