“Catch and release” of the CpN3 ligand using cobalt: dissociation, protonation, and C–H bond thermochemistry

Abstract

Coordination of the amine-rich CpN3 ligand to cobalt is reported. Ligand displacement leads to ligand protonation and evaluation of the metal-free C–H bond thermochemistry, revealing a weak homolytic C–H bond dissociation free energy (52 kcal mol−1).
