Ruthenium-mediated cyclodimerisation of buta-1,3-diene
Abstract
Treatment of solvated Ru2+ ions in acetone solution with a large excess of buta-1,3-diene results in the formation of the unusual cyclooctatriene/cyclooctadienyl complex [Ru(η6-C8H10)(1-3:5-6-η-C8H11)]+ 1 derived from the cyclodimerisation and dehydrogenation of two pairs of butadiene molecules at the metal center.
