Abstract

ABSTRACT Palladium complexes were obtained by reaction of phosphine-linked cyclophosphazenes,(P 3 N 3)(OC 6 H 4-PR 2) 6, where R= phenyl, i-propyl or cyclohexyl, with using a Pd/ligand molar ratio of 3/1. The (P 3 N 3)(OC 6 H 4-PR 2) 6 Pd 3 (dba) x complexes were characterized by elemental analyses, mass spectrometry, 31 P NMR and FT-IR where a characteristic ν C= C band of dba coordinated to palladium was always ...
