A robust acenaphthoimidazolylidene gold complex is demonstrated as a highly efficient catalyst in the direct alkylsulfonylation of boronic acids. Remarkably, a wide range of highly reactive and unreactive C-electrophiles were well-tolerated to produce various (hetero)aryl-alkyl, aryl-alkenyl, and alkenyl-alkyl sulfones in satisfactory yields with 5 mol % catalyst loading. Along with the steric properties of NHC ligands, the high catalytic activity of this gold complex suggests that the strong σ-donation of acenaphthoimidazolylidene also played a role in promoting this challenging redox-neutral catalytic process.
