  Synthesis of and ethylene oligomerization with binuclear palladium catalysts having sterically modulated bis-imine ligands with methylene spacer

  摘要：

  Sterically modulated bis-imine ligands (L-1-L-3) were prepared by reacting 4,4'-methylene bis-(2,6-dialkyl aniline) and antipyrine-4-carboxaldehyde in a 1: 2 stoichiometric ratio. The reactions of L-1-L-3 with dichloro(cycloocta-1.5-diene) palladium(II) [PdCl2(cod)] yield the corresponding binuclear palladium complexes with the general formula Pd2Cl4L (L = L-1, L-2, and L-3). The binucleating ligands bind to the palladium ion via the lone pair on the imine nitrogen and amide oxygen atoms, resulting in a square-planar geometry around the metal center. All the palladium catalysts efficiently oligomerize ethylene to produce C-4-C-20 fractions at activities of up to 1308 kg-oligomer mol-Pd-1 bar(-1) h(-1) at 30 degrees C in combination with ethylaluminum sesquichloride. The formation of active sites by the change in geometry of the metal complexes could be traced using spectroscopic and electrochemical techniques. (C) 2011 Elsevier B.V. All rights reserved.
