A one-step method to convert nitroarenes into aryl sulfones under operationally simple, transition-metal-free conditions is described. A range of nitroarenes were reacted with sodium sulfinates and caesium carbonate in N,N′-dimethylpropyleneurea to afford aryl sulfones in up to 83% yield.
An efficient cross-coupling of aryl bromides with sodium sulfinates, using an organoboron photocatalyst with nickel, is described herein. Under the irradiation of white light, this dually catalytic system enables the synthesis of a series of sulfone compounds in moderate to good yields. A broad range of functional groups and heteroaromatic compounds is tolerated under these reaction conditions. The
