title: A straightforward alkynylation of Li and Mg metalated heterocycles with sulfonylacetylenes.
abstract: Coupling of alkynyl moieties to heterocyclic rings, without using transition metals, can be easily performed by the reaction of aryl or heteroaryl sulfonylacetylenes with heteroaryl-Li compounds or their corresponding less reactive magnesium derivatives.
