Ligand architecture and secondary‐sphere effects in a well‐defined cobalt(IV)–oxo complex

open access: yesBulletin of the Korean Chemical Society, EarlyView.
A well‐defined cobalt(IV)–oxo complex supported by a neutral tetraazamacrocyclic ligand is generated and fully characterized. The cobalt(IV)–oxo species exhibits electrophilic oxygen‐atom and hydrogen‐atom transfer reactivity, strongly modulated by protonation and secondary coordination sphere effects, providing new insight into structure–reactivity ...
