摘要: Abstract A series of new cationic cyclopalladated complexes 2–6 have been synthesized from neutral complex 1 p-tert-butyl-calix[4]arene bisphosphite with various nitrogen donor ligands (acetonitrile, pyridine, aniline, (R)-(+)-1-phenylethylamine and 4,4′-bipyridine) in presence Ag(OSO2CF3) as a chloride scavenger. These characterized by NMR spectroscopy. Single crystal X-ray diffraction studies performed on 3 6 solid state reveal nearly square planar geometry around the metal distorted cone conformation calix[4]arene framework. based hetero having variable steric electronic properties could be efficient catalysts for important organic transformation reactions.
