Ojha, Subhadra published the artcilePd-Catalyzed desulfitative arylation of olefins by N-methoxysulfonamide, Category: catalysis-chemistry, the publication is Organic & Biomolecular Chemistry (2022), 20(6), 1292-1298, database is CAplus and MEDLINE.
A novel Pd-catalyzed protocol for the desulfitative Heck-type reaction of N-methoxy aryl sulfonamides with alkenes was reported. The cross-coupling reaction was performed successfully with a variety of olefins to obtain aryl alkenes RCH=CHR1 [R = Ph, 4-ClC6H4, 2-thienyl, etc.; R1 = CN, COOH, CO2Me, etc.]. Different substituents on the aromatic ring of N-methoxysulfonamides were also found to be compatible with the reaction conditions. Expectedly, the reaction proceeded through CuCl2-promoted generation of the nitrogen radical and subsequent desulfonylation under thermal conditions to afford the aryl radical for the Pd-catalyzed coupling reaction. N-Methoxysulfonamide was further exploited for the synthesis of sym. biaryls in the presence of CuCl2.
