In heterogeneous catalysis, the catalyst is in a different phase from the reactants. name: Tris(dibenzylideneacetone)dipalladium-chloroform, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 52522-40-4, name is Tris(dibenzylideneacetone)dipalladium-chloroform. In an article£¬Which mentioned a new discovery about 52522-40-4

Self-adaptable catalysts: Substrate-dependent ligand configuration

Pd(II) allyl and Pd(0) olefin complexes containing the configurationally labile ligand 1,2-bis-[4,5-dihydro-3H-dibenzo[c-e]azepino]ethane were studied as models for intermediates in Pd-catalyzed allylic alkylations. According to NMR and DFT studies, the ligand prefers Cs conformation in both eta3-1,3-diphenylpropenyl and eta3-cyclohexenyl Pd(II) complexes, whereas in Pd(0) olefin complexes it adopts different conformations in complexes derived from the two types of allyl systems in both solution and, as verified by X-ray crystallography, in the solid state. These results demonstrate that the Pd complex is capable of adapting its structure to the reacting substrate. The different structural preferences also provide an explanation for the behavior of 1,3-diphenyl-2-propenyl acetate and 2-cyclohexenyl acetate in Pd-catalyzed allylic alkylations using pseudo-C 2 and pseudo-Cs symmetric ligands.
