eng Synthesis and characterization of novel enaminone metal complexes Metal complexes of enaminones are versatile and readily obtainable species which chemistry has received considerable attention in recent years. These species can be usually used for carbon dioxide activation1, polymerization of ethylene2 or aryl-aryl couplings3. Probably the easiest way of preparation of enaminone ligands is the condensation reaction of acetylacetone and the primary amine derivative in the molar ratio 1:1 with a catalytic amount of p-toluensulfonic acid4. The synthesis of target metal complexes via deprotonation of a parent enaminone is the major synthetic procedure described in the literature4 but preparation of complexes from neutral ligand and suitable reagents are also known5. Several complexes were synthesized from metal chlorides (M=Sn, Ge, Pb, Zn) or diethyl zinc or bis[bis(trimethylsilyl)]amide metal complexes (M=Sn, Pb, Ge) and characterized by multinuclear NMR spectroscopy and when it was possible by XRD techniques. enaminone; complexes; NMR spectroscopy, XRD techniques
