  • NCN trianionic pincer complexes as catalysts for olefin polymerization and isomerization
    Patent number: 9637425
    Abstract: A catalyst comprising a NCN pincer ligand group VI complex is capable of being used as an olefin polymerization or isomerization catalyst that does not require an expensive cocatalyst. The complex has the NCN pincer ligand in a trianionic form with the group VI in the +3 oxidation state or the +4 oxidation state and complexed to an anionic hydrocarbon group, or the complex has the NCN pincer ligand in a dianionic form with the group VI in the +2 oxidation state. The complex is capable of initiating the polymerization of alkenes without an added activator. The presence of a water scavenger and activator or cocatalyst, such as triisobutylaluminum, increases the catalytic activity. The complex is capable of selectively isomerizing 1-alkenes to cis/trans 2-alkenes.

  • Trianionic pincer ligands, a CR(III)/CR(V) catalytic system and its use for catalytic aerobic oxidation of organic substrates
    Patent number: 8846950
    Abstract: An embodiment of the invention is a novel Cr(V)OCO3? trianionic pincer ligand complex. Another embodiment of the invention is a catalytic method for oxidation of a substrate aerobically in the presence of a source of oxygen, where the novel Cr(V)OCO3? trianionic pincer ligand complex acts as the catalyst. The substrate can be a phosphine, amine, sulfide, alkene, alkane or a second metal complex. Another embodiment of the invention is directed to NCN pincer ligands that can form trianionic pincer ligand complexes.
