Nambo, Masakazu published the artcileDevelopment of Versatile Sulfone Electrophiles for Suzuki-Miyaura Cross-Coupling Reactions, Recommanded Product: 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride, the publication is ACS Catalysis (2017), 7(2), 1108-1112, database is CAplus.
The development of fluorinated sulfone derivatives as versatile electrophiles for Suzuki-Miyaura cross-coupling reactions is described. Introducing electron-withdrawing groups on the aryl ring of the sulfone facilitates the Pd-catalyzed activation of the C-SO2 bonds. Cross-coupling reactions with fluorinated sulfone electrophiles are reported, leading to a variety of multiply arylated products in good yields. The reactivity of this unusual electrophile is benchmarked vs. common electrophiles and its use in iterative cross-couplings for concise synthesis of biol. active mols. is described.
