The invention provides a chiral bisoxazoline ring carbene rare earth metal catalyst, a preparation method and an application, and belongs to the technical field of catalysis. The chiral bisoxazoline ring carbene rare earth metal catalyst uses aminoalcohol and diethyl oxalate as initial raw materials, the raw materials are cheap and easy to obtain, and is easy to modify; the preparation method of the chiral bisoxazoline ring carbene rare earth metal catalyst, wherein The carbene ligand can directly react with rare earth metals without separation, the catalyst is easy to separate and purify, and the yield is high; the catalytic system composed of chiral bisoxazoline ring carbene rare earth metal catalyst and organoboron salt is used to catalyze linear olefins, rings Homopolymerization of olefins and alkynes can produce a series of new polymer materials with specific structures. |
