Bridged amidine divalent lanthanide complexes Synthesis
In this paper, two-amidine as a bridging ligand (L = [Me3SiNC (Ph) N (CH2) 3NC (Ph) NSiMe3]), synthesized a series of bridged bivalent amidine, trivalent double metal, single rare earth metal complexes and lithium oxide containing divalent rare-earth clusters, these complexes have been X-ray diffraction, including comprehensive analysis, including characterization. We looked at some of the complex and the lithium salt bridge amidine amine and nitriles in the catalytic reaction of amidine catalytic activity. The main results are as follows:
