Synthetic Route of 32005-36-0, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 32005-36-0, Name is Bis(dibenzylideneacetone)palladium, molecular formula is C34H28O2Pd. In a Article,once mentioned of 32005-36-0

We have developed a novel method for synthesizing trisubstituted cyclopropane derivatives by a palladium-catalyzed intramolecular allylic alkylation of alpha-aryl esters. By using alpha-aryl alpha-(methoxycarbonyl) gamma-vinyl gamma-lactones as substrates, decarboxylative formation of pi-allylpalladium(II) intermediates followed by an intramolecular allylic alkylation of the ester enolates proceeded in the presence of 5 mol% of a palladium catalyst, producing 1-aryl-1-(methoxycarbonyl)-2-vinylcyclopropanes in good to excellent yields and high diastereoselectivities. The relative configuration of the major isomer was determined by transforming the product into a known intermediate of milnacipran synthesis. When we extended our method to asymmetric catalysis, we obtained methyl (1S,2S)-1-phenyl-2-vinylcyclopropanecarboxylate in up to 55% ee by using (S)-[2?-(diphenylmethoxy)-1,1?-binaphthalen-2-yl](diphenyl)phosphine as a chiral monodentate phosphorus ligand.
