Abstract

Recrystallization of bis(dibenzylideneacetone)palladium from various solvents affords novel binuclear palladium-dibenzylideneacetone complexes of composition Pd2(Dibenzylideneacetone)3(Solvent). These new complexes were identified by spectroscopic (IR, NMR, UV, and mass) and thermogravimetric analyses, together with a confirmative crystallographic structure determination. The CC bonds of a given dibenzylideneacetone ligand coordinate separately to two palladium atoms to yield a binuclear complex in which each palladium atom exhibits trigonal coordination. The Pd-Pd distance is 3.245 Å. Ligand exchange reactions, oxidative addition reactions, and complex formation reactions with p- and o-quinones were investigated and found to yield a variety of new organopalladium complexes.
