[reaction: see text]. When a CH2Cl2 solution of an enyne containing the cycloalkene moiety was stirred in the presence of ruthenium-carbene complex (10 mol %) at room temperature under ethylene gas (1 atm), ring-opening and ring-closing metathesis occurred to afford cyclized triene. The reaction was carried out under argon gas, and no cyclized product was obtained. Enynes with a terminal alkyne gave good results.
