Vinylation of azoles: The cationic RuII complex, [RuCl(PPh3)(dppe)(CH3CN)2][BPh4], is an efficient catalyst for regio‐ and stereoselective vinylation of azoles by alkynes (dppe=diphenylphosphinoethane; see scheme). Only 0.5 mol % of the complex is required and the reactions do not require stringent exclusion of moisture and air.
