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