| titleOfInvention | A kind of pincer rare earth complex and its synthesis method and application |
| abstract | The pincer rare earth complex and its synthesis method and application of the invention belong to the technical field of organic synthesis and application. The synthesis method of pincer-like rare earth complexes is to use Schiff base compounds as ligands, first lithiate with lithium reagents, and then transfer metallization with rare earth halides or tetrahydrofuran adducts of rare earth halides, and finally remove the solvent in a vacuum, and the residual The product was extracted with toluene, and the toluene solution was concentrated to obtain pincer-shaped rare earth complexes. The purpose of the pincer rare earth complex is to catalyze the selective polymerization of butadiene or isoprene monomer under the activation of alkylaluminum or the joint activation of alkylaluminum and organic boron salt. The pincer-shaped rare earth complex of the present invention has novel structure and high synthesis yield; when used to catalyze the polymerization of isoprene or butadiene, it has moderate activity and high stability, and the obtained polyisoprene or polybutadiene cis-1 ,4 The selectivity is higher. |
