Quinoline binding mode as a function of oxidation state in aryloxide-supported tantalum complexes: Models for hydrodenitrogenation catalysis
Kevin D. Allen,Michael A. Bruck,Steven D. Gray,Richard P. Kingsborough,David P. Smith,Keith J. Weller,David E. Wigley +6 more
TL;DR: In this paper, a two-electron reduction of these complexes, an η 1 (N ) → η 2 (N,C ) bonding rearrangement is effected and the thermally sensitive, d 2 species [η 2( N,C) )-QUIN]Ta(OAr) 3 Cl 2 (OEt 2 ) and 6MQ = 6-methylquinoline (6MQ) are prepared from pentane.

Tetrahydroquinolinyl amido and indolinyl amido complexes of tantalum as models for substrate-catalyst adducts in hydrodenitrogenation catalysis
TL;DR: In this article, a trigonal bipyramidal geometry with equatorial amido ligands that are closer to lying parallel (within) than perpendicular to the TBP equatorial plane was determined for Ta(NC9H10)2Cl3 (2).

Structural Models for the Substrate−Catalyst Adduct in Hydrodenitrogenation Catalysis: Oxygen vs Sulfur Ligation
Peter A. Fox,Michael A. Bruck,Steven D. Gray,Nadine E. Gruhn,and Carina Grittini,David E. Wigley +5 more
TL;DR: In this paper, a comparison between models for the substrate−catalyst adduct in hydrodenitrogenation (HDN) catalysis is made with respect to oxygen vs sulfur ancillary ligands.
