Abstract

The isomerization of 1-pentene to cis-2-pentene and trans-2-pentene is catalyzed by Ru₃(CO)₁₂ in nonpolar solvents and the initial rate dependence from the Ru₃(CO)₁₂ and CO concentration is discussed. Addition of acids such as acetic acid increases the conversion rate; in both cases mechanisms involving π-allyl intermediates are suggested. Dehydrogenation by Ru₃(CO)₁₂ of the pentene equilibrium mixture yields the hydrides H₄Ru₄(CO)₁₂ and H₂Ru₄(CO)₁₃ and two isomers of molecular formula HRu₃(CO)₉C₅H₇, as main products. These two complexes were characterized by spectral methods and their behavior in reactions with hydrogen and Ru₃(CO)₁₂ is described.
