چکیده
The reaction of 1,3-bis(4,6-dimethylpyridyl-2-imino)isoindoline and palladium acetate in methanol selectively yields the expected acetato palladium N,N,N-chelate or a cyclometalated tetranuclear dimer depending on the stoichiometry of the reactants.

The title compound, [Pd(2)(C(13)H(8)N(2)O(2))(C(15)H(11)O(2))(2)], crystallized from a mixture of ethanol and n-hexa-nes. The structure is the first example of β-diketonate in a dianionic κ(2)C-coordination complex containing a Pd(II)-Pd(II) bond. Both Pd(II) atoms adopt a pseudo square-planar coordination geometry. The mol-ecular packing involves π-inter-actions between the phenyl rings of the...

The asymmetric unit of the title complex, [PdCl(2)(C(12)H(16)N(3)O)]·0.5C(4)H(8)O, consists of one palladium complex in a general position and one half tetra-hydro-furan (THF) solvent mol-ecule, with the O atom lying on a twofold rotation axis. The Pd(II) atom is bound to one chelating imino nitroxide radical through two N atoms, one from the pyridyl ring and the other from the imidazoline ring...
متن کاملStructural Aspects of Palladium Systems Used as Catalyst Precursors in CO/olefins co- and ter-Polymerisation Reactions
The synthesis and characterisation of three palladium complexes, involved in the homogeneous catalysis towards the CO-olefins coand ter-polymerisation reactions, are reported. The Pd (dpk·CH3OH) (CF3CO2)2 (1), (dpk = di(2-pyridyl) ketone) and Pd (dppp)(bipy) B(C6F5)4 2 (2), (bipy = 2,2’-bipyridine, dppp = 1,3-bis(diphenylphosphino)propane) compounds are examples of a neutral complex and of a di...

The structure of 1 may be considered coordination polymer of lead(II) and Single crystal X–ray analysis of compound ...
متن کاملNew chiral P-N ligands for the regio- and stereoselective Pd-catalyzed dimerization of styrene.
Two new chiral, enantiomerically pure, hybrid P-N ligands, namely (2R,5S)-2-phenyl-3-(2-pyridyl)-1,3-diaza-2-phosphanicyclo[3,3,0]octan-4-one (1) and (2R,5S)-2-phenyl-3-(2-pyridyl)-1,3-diaza-2-phosphanicyclo[3,3,0]octane (2), have been synthesized starting from L-proline. The two ligands differ in the presence or not of a carbonyl group in the diazaphosphane ring. Their coordination chemistry t...
