Synthesis and characterization of palladium(II)-phosphole and – biphosphole complexes. Regulation of the homoleptic coordination environment of square-planar palladium(II)
A series of novel square-planar palladium(II)-phosphole complexes was synthesized in good yields by a ligand-substitution reaction of [Pd(CH3CN)4](BF4)2 with 3,4-dimethyl-1-phenylphosphole (dmpp) and/or 3,3’4,4′-tetramethyl1,1′-diphenyl-2,2′-biphosphole (bidmpp) in CH2Cl2; [Pd(dmpp)4](BF4)2 (1), [Pd(bidmpp)(dmpp)2](BF4)2 (2), and [Pd- (bidmpp)2](BF4)2 (3). Those complexes were characterized by 1H and 31 PNMR spectroscopies and X-ray crystallography for 3. The crystal structure of 3 revealed that the configurations of the phosphorus atoms were (R, R, S, S), indicating that the structure was a meso form with an intramolecular pi-pi interaction between the phenyl groups. 1HNMR spectroscopy suggested the structures of 1 and 2: Complex 1 has a water wheel-like C(4h) structure and complex 2 is C2 symmetric. In the 31PNMR spectra of those complexes, each resonance showed a smaller downfield shift than that observed for [Pd(dppe)2]Cl2 (dppe = 1,2-bis(diphenylphosphino)ethane), indicating that the palladium-phosphole interaction is governed by mainly a sigma-donation, and that there is a small contribution from a pi-back bonding interaction.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 21797-13-7
