Influence of substituents on the chemical shift of fluorine in certain fluorosubstituted arylphenylmercury compounds and N-arylmercury derivatives of benzenesulfonanilide
A one-potthree-componentreaction involving nitroarenes, (hetero)arylboronic acids, and potassium pyrosulfite leading to sulfonamides was described. A broad range of sulfonamides bearing different reactive functional groups were obtained in good to excellent yields through sequential C-S and S-N coupling that does not require metal catalysts.
The invention provides methods and compositions relating to novel pentafluorophenylsulfonamide derivatives and analogs and their use as pharmacologically active agents. The compositions find particular use as pharmacological agents in the treatment of disease states, particularly cancer, vascular restenosis, microbial infections, and psoriasis, or as lead compounds for the development of such agents. The compositions include compounds of the general formula I:

highly efficient method for nickel‐catalyzed C−N bond formation between sulfonamides and aryl electrophiles. This technology provides generic access to a broad range of N‐aryl and N‐heteroaryl sulfonamide motifs, which are widely represented in drug discovery. Initial mechanistic studies suggest an energy‐transfer mechanism wherein C−N bond reductive elimination occurs from a triplet excited NiII complex
