One-electron. oxidation. of otherwise unreactive ((1:4,5-eta)-1,4-pentadien-1-yl)ruthenium carbonyl complexes in acetonitrile under carbon monoxide Leads to the formation of 5-methylene-2-cyclopenten-1-ones via carbonylation, migratory cyclization, and beta-hydride elimination. Oxidation in dichloromethane produces an acyclic 1,4-pentadiene, even under a carbon monoxide atmosphere.
