Robust N-heterocyclic carbene palladium complexes are highly efficient catalysts for direct alkylsulfonylation of (hetero)aryl- or alkenyl-boronic acids with potassium metabisulfite and (hetero)alkyl-halides. Among them, acenaphthoimidazolylidene palladium(II) complexes exhibited the highest activities, and up to quantitative yields were obtained for diverse structurally distinct sulfones under very mild reaction conditions.

Pd（NHC）催化的硼酸烷基磺酰化：合成砜的通用有效方法

健壮的N-杂环卡宾钯络合物是高效的催化剂，可用于（杂）芳基-或烯基-硼酸与亚硫酸氢钾和（杂）烷基卤化物的直接烷基磺酰化。其中，并咪唑基亚钯钯（II）配合物表现出最高的活性，并且在非常温和的反应条件下，不同结构的砜获得了最高的定量收率。
