The commercially available Fe (III) and Ru (II) porphyrin complexes Fe (TPP) Cl and Ru
(TPP)(CO) are efficient catalysts for selective olefination of a variety of aldehydes with ethyl
diazoacetate in the presence of triphenylphosphine. The reactions were carried out under
mild conditions in a one-pot fashion with the use of a stoichiometrical amount of EDA, which
proceeded with excellent yields and high (E)-selectivity. Air atmosphere, low catalyst
loadings, and functional group tolerance were also demonstrated.
