Abstract An efficient decarboxylative sulfonylation of arylacetylenic acids with sodium arylsulfinates has been achieved by an electro-oxidative strategy. This novel protocol offers a simple, efficient, and green route to a series of arylacetylenic sulfones in moderate yields under metal-free and external oxidant-free conditions. Graphical Abstract
An efficient synthesis of diversely functionalized furans is developed via Cu-mediated intermolecular annulative couplings of acetylenic sulfones and activated methylenes, which provides a straightforward and atom-economic way to tetrasubstituted furan derivatives in good yields.

An efficient and mild route for the formation sulfur or phosphor-substituted alkynes was herein demonstrated. The Mukaiyama reagent-mediated transformation started from easily-accessible substrates without carbon-carbon triple bonds, and the reaction proceeded undermildconditions (room temperature) in a one-pot manner, requiring for no transition metal-catalysts. The practical protocol featured for
