Copper‐catalyzed one‐pot conversion of thiols to olefins was conducted under aerobic conditions. Thiols were oxidized to generate thioaldehydes, which reacted with sulfones or phosphorousylides to form the corresponding olefins. The formation of thiosulfonates and phosphorous sulfides confirms that these olefination protocols proceed via thioaldehyde‐sulfone and thioaldehyde‐ylide adducts.

decarboxylative sulfonylation of β-keto acids with sodium sulfinates is developed. The transformation exhibits a broad substrate scope and good functional group tolerance. Preliminary mechanistic studies showed that this reaction is likely to proceed through a nucleophilic substitution of β-keto acid with sulfonyl bromide pathway. All synthesized β-keto sulfones were evaluated the inhibitory effect against human

The nickel-catalyzed [small alpha]-benzylation of sulfones with readily available benzylic alcohol derivatives was achieved via C-O activation. The transformation was complete in 30 minutes using a simple Ni(COD)2 as a catalyst...
sulfones with terminal alkynes gave unsaturated δ-keto sulfones in good to excellent yields under rhenium catalysis. In this reaction, the insertion of the alkynes into the nonstrained carbon–carbon single bond between the α- and β-positions of the β-keto sulfones proceeded smoothly, and (Z)-isomers were produced with high regio- and stereoselectivities.
