This study investigates the activation barriers of reductive elimination (RE) pathways in Co(IV) cobaltacycles, correlating them with quantified interatomic noncovalent interactions. Using the Independent Gradient Model (IGM)/Intrinsic Bond Strength Index (IBSI) method, the researchers analyzed the role of noncovalent interactions in Co(IV) [Cp*Co(phpy)X] complexes, where phpy is 2-phenylenepyridine and X is a ligand. The study shows that the activation barrier of the RE pathway correlates directly with the IBSI of the X-to-carbanionic chelate's carbon. This correlation suggests that in silico prediction of which -X ligand is more prone to operate an efficient Cp*Co-catalyzed directed X-functionalization of aromatic C-H bonds is feasible. Experimental results support this theoretical conclusion. The study also explores the role of dispersion forces and noncovalent interactions in understanding molecular cohesion and chemical reactivity of organometallic molecules. It highlights the importance of noncovalent interactions in agostic reactant complexes for effective C-H bond activation. The research focuses on the Co(III) to Co(IV) oxidation and its effect on the activation barriers of RE and cyclocondensation (CC) pathways. The results show that the activation energy for RE in the Co(IV) state is significantly lower than in the Co(III) state, indicating that the Co(IV) state is more favorable for RE. The IBSI values for the C2'-X interaction correlate well with the RE activation barriers, suggesting that stronger interactions lead to lower activation barriers. The study also finds that systems with higher IBSI values are more likely to undergo RE than CC. The experimental data support the theoretical findings, showing that systems with higher IBSI values yield RE products upon oxidation, while those with lower IBSI values tend to undergo hydro-de-metalation or CC. The study concludes that the IBSI is a reliable descriptor for predicting the reactivity of Co(IV) [Cp*Co(phpy)X] systems towards RE.This study investigates the activation barriers of reductive elimination (RE) pathways in Co(IV) cobaltacycles, correlating them with quantified interatomic noncovalent interactions.
