Ruthenium-catalyzed ROM-RCM of cycloalkene-yne.
[formula: see text] ROM-RCM (ring-opening and ring-closing metatheses) of cycloalkene-yne was demonstrated using a second-generation ruthenium complex. When cycloalkene bearing the alkyne moiety at the C-1 position was reacted with a ruthenium-carbene complex under an atmosphere of ethylene, ROM-RCM proceeded smoothly to give bicyclic compound and/or dimeric compound in good yields.
