A simple copper-catalyzed alkyl–alkynyl cross-coupling strategy has been developed using the reaction between alkynyl bromides and alkylzirconocenes. The alkylzirconocenes were generated in situ via regioselective addition of Schwartz's reagent (ZrCp2HCl) on to alkenes. The reaction has a broad scope, a range of functionalized bromoalkynes and alkylzirconium reagents were successfully coupled, resulting in moderate to good yields of the desired internal alkynes.

A one-pot synthesis of β-dimethylsulfonium-substituted vinyl triflates by the reaction of dimethyl sulfide ditriflate with acetylenes is described. β-Dimethylsulfonium-substituted vinyl triflates were found to exhibit unusual reactivity towards nucleophil
