Reaction of equimolar amounts of μ-1-3-η:6-8-η-octadienatobis(1,1,1,5,5,5-hexafluoroacetylacetonatopalladium) and triisopropylphosphine gives a bimetalic octadienyl-bridged complex, in which one palladium atom is η¹-bound to the terminal carbon of the octadienyl chain.Insertion of CO2 into this Pd-C bond gives a carboxylate complex; acidic decomposition and hydrogenation of the carboxylate complex gives pelargonic acid.The results are discussed in relation to the mechanism of the palladium-catalyzed reaction between butadiene and carbon dioxide.
