To solve such problems and retain reactive versatility, rare earth complexes supported by a variety of tridentate PNP pincer ligands have been explored. Such complexes can serve as perfect precursors for preparing ultra-active rare earth species containing two metal-carbon bands, let alone Ln=N and Ln=P multiple bonds. In addition, the combined stability and activity of the cation rare earth mediates made them the best catalysts for the polymerization of olefins and other non-polar hydrocarbon monomers, especially conjugated dienes. The practical utilization of rare earth metal catalysts for new materials production have also extensively explored by experts from the academic and industries. }, keywords = {PNP ligand,rare earth metals,Lanthanides,Reactivity,catalysis}, url = {http://poj.ippi.ac.ir/article_1947.html}, eprint = {http://poj.ippi.ac.ir/article_1947_fdde28ad13e047c18a464e70d6696b1c.pdf} }
