Interpretive Summary:

Technical Abstract: A new facile Ru-catalyzed route to bio-olefins3 from unsaturated fatty acids via readily accessible metal-as-ligand type catalyst precursors, [Ru(CO)2RCO2]n and Ru3(CO)12, will be described. The catalyst apparently functions in a tandem mode by dynamically isomerizing the positions of double bonds in an aliphatic chain and, subsequently, decarboxylating specific isomers with lower activation barriers. A mechanistic pathway with supporting evidence for this novel catalytic chemistry will be presented. This approach offers new technology for converting bio-based fatty acids into useful industrial chemical intermediates.
