BIS(PHOSPHINE)-CARBODICARBENE CATALYST COMPLEXES AND METHODS OF USING THE SAME

An organometallic complex of a tridentate bis(phosphine)-carbodicarbene ligand and a transition metal, is described. In some embodiments the ligand has the structure of Formula (I): The complexes are useful in methods of making an allylic amine carried out by reacting a 1,3-diene with a substituted amine in the presence of such an organometallic complex to produce by intermolecular hydroamination the allylic amine.

ENANTIOSELECTIVE C-H AMINATION WITH IRON PHTHALOCYANINE AND DIAMMONIUM TEMPLATE CATALYSTS
20250352988 · 2025-11-20 ·

Described herein are catalytic systems that can catalyze enantioselective CH functionalization reactions and methods of using thereof are described. These catalytic systems contain iron complexes as host catalysts and diammonium guest templates as co-catalysts. The iron-based host catalysts contain crown-ether phthalocyanine ligands. The diammonium guest templates are bidentate compounds with chirality. The iron-based host catalysts and the bidentate ammonium guest templates can provide a complex steric environment with the for stereospecific and site-selective CH functionalization, such as CH amination. For example, enantioselective CH amination reaction performed using the disclosed methods can achieve high enantiomeric ratio (i.e., at least 2:1) and optionally high yield (i.e., at least 30%).
