Abstract

The mechanism of styrene polymerization by α‐diimine iron complexes correlates with the metal spin state of the catalyst. Experimental and theoretical studies indicate that high‐spin catalysts are halogenophilic, resulting in atom transfer radical polymerization (ATRP), while intermediate‐spin complexes are carbophilic giving rise to catalytic chain transfer
