Highly Selective Synthesis of <i>ctt</i>-1,5,9-Cyclododecatriene from 1,3-Butadiene via Nitrogen-Ligand-Supported Titanium Catalysts: Experimental Optimization and Mechanistic Insights.

ABSTRACT: Facing global energy and environmental challenges, transportation industries are adopting lightweighting as a key strategy to improve energy efficiency. Nylon12 is a crucial material in lightweight applications. However, 1,5,9-cyclododecatriene (1,5,9-CDT) serves as a key intermediate in its synthesis, and the preparation methods of 1,5,9-CDT currently still suffer from low catalytic activity and insufficient conversion, coupled with a lack of mechanistic studies on macrocyclic formation. To address these challenges, this study focuses on the key synthesis technology of 1,5,9-CDT by designing and preparing four novel nitrogen-ligand-supported transition metal catalysts (Cat.1-Cat.4). Using 1,3-butadiene as the monomer, the effects of the catalyst performance and reaction conditions on the
