Abstract
The synthesis and characterization of palladacycloheptane and palladacyclononane complexes based on 1,5-cyclooctadiene (COD), 2,2'bipyridine (bipy), triphenylphosphine (PPh3), and 1,2-bis(diphenylphosphino)ethane (dppe), and their precursors were successfully carried out. The complexes were characterized by 1H, 13C and 31p NMR spectroscopy, mass spectrometry as well as elemental analysis. The palladacycloalkanes were prepared from the bis(alkenyl) complexes of the type cis-[Pd{(CH2)nCH=CH2hL21 (n = 2, 3; L = PPh3; L2 = COD, bipy, dppe) by ring closing metathesis (RCM) reactions followed by hydrogenation.
