| Research Abstract |
By use of the cationic half-sandwich rare earth alkyl catalysts, we have achieved the regio- and stereoselective copolymerization of various olefins to give new polymer materials that cannot be prepared by previous means. The cationic half-sandwich rare-earth alkyl complexes can also serve as unique catalysts for the addition of ortho-C-H bonds of various pyridines and anisoles to a variety of olefins, to afford new alkylated pyridine and anisole derivatives, respectively.
We have synthesized a new family of heteromultimetallic polyhydride complexes and group 4 metal polyhydride complexes, and found that rare-earth/d-transition metal heteromultimetallic polyhydride complexes and a trinuclear titanium hydride cluster show reversible hydrogen addition and release reaction, and unprecedented dinitrogen activation, respectively.
