Arylboronic acids, substituted in o-, m- and p-positions with SO2F group were prepared according to efficient and practical procedure as reagents for Suzuki coupling with aryl halides for synthesis of versatile arenesulfonyl fluorides. The syntheses of the para- and meta-isomers commence with the appropriate bromo-substituted benzenesulfonyl chlorides, and the ortho-isomer is prepared from benzenesulfonyl fluoride. The boronic acids undergo efficient Suzuki-Miyaura coupling reactions with a range of aryl halides. We also report an efficient Rh(I)-catalyzed conjugate addition reaction using the para-substituted boronic acid. In the experiment, the researchers used many compounds, for example, 2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (cas: 68716-49-4Related Products of 68716-49-4).
2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (cas: 68716-49-4) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Related Products of 68716-49-4
