Abstract
The ring size effect of macrocyclic TMC ligands in nonheme iron(IV)-oxo complexes has been examined in hydrogen atom transfer (HAT) and oxygen atom transfer (OAT) reactions; an iron(IV)-oxo complex bearing a smaller TMC ligand is more reactive in both HAT and OAT reactions, resulting from its high Fe(IV/III) redox potential.
摘要
大环 TMC 配体在非血红素铁(IV)-氧配合物中的环大小效应已在氢原子转移 (HAT) 和氧原子转移 (OAT) 反应中进行了研究; 带有较小 TMC 配体的铁(IV)-氧配合物在 HAT 和 OAT 反应中都更具反应性，这是由于其高 Fe(IV/III)氧化还原电位。
