A new active three-component catalytic system for enyne metathesis is reported. It is easily generated in situ by combination of [RuCl2(p-cymene)]2, 1,3-bis(mesityl)imidazolium chloride and Cs2CO3 and exhibits excellent performance for the intramolecular metathesis reaction even from highly substituted enynes.
