A one-pot nickel-catalyzed synthesis of (hetero)aryl alkyl sulfones from readily available boronic acids, sodium metabisulfite and benzylic ammonium salts as electrophiles is described. This general and efficient synthetic process is of broad scope, occurs in two steps, and delivers structural diverse sulfones, and the intermediate sulfinate is isolated. The transformation exhibits application of benzylic ammonium salts as novel electrophiles for direct insertion of SO2 as a novel area to be investigated.

A practical and efficient approach adopting transition-metal-free cross-coupling of sulfonyl hydrazides with benzyl ammonium salts has been developed to synthesize benzyl sulfones using Cs2CO3 as base under mild conditions. The protocol employs stable and easy to handle coupling partners, and is endowed with good substrate compatibility, leading to functional benzyl sulfones in good yields.

(Chemical Equation Presented) The nucleophilic substitution of benzylic carbonates with sodium arenesulfinates was catalyzed by the palladium complex generated in situ from [Pd(η3-C3H5)Cl] 2 and DPEphos [bis(2-diphenylphosphinophenyl)ether]. The catalytic reaction proceeded in DMSO at 80°C and gave a variety of benzylic sulfones in high yields.
