Palladium-Catalyzed Coupling Reactions of Diarylvinylidenecyclopropanes with 2-Iodophenol and N-(2-Iodophenyl)-4-methylbenzenesulfonamide

摘要

A palladium-catalyzed cross-coupling reaction of diarylvinylidenecycloproparies with 2-iodophenol and N-(2-iodophenyl)-4-methylbenzenesulfonamide provided a variety of cyclopropane-containing 2,2-diaryl-3-tetramethylcyclopropyhdene-2,3-dihydrobenzofuran and 2,2-diar-yl-3-tetramethylcyclopropylidene-1-(toluene-4-sulfonyl)-2,3-di hydro-1H-indole derivatives in moderate-to-good yields.
