Iron(II) complexes bearing monoanionic tridentate salicyladiminato ligands are shown to be highly efficient catalysts for atom transfer radical polymerization (ATRP). Polymerization rates for styrene are among the highest reported for iron-mediated ATRP in nonpolar media, correlating well with E1/2 potentials and DeltaEp values for the complexes. The rigidity of the tridentate ligands, combined with ample space around the metal center to accommodate a halogen atom, we believe to be an important factor in the efficient ATRP behavior of these systems.
带有单阴离子三齿水杨醛亚胺配体的铁（II）配合物被证明是原子转移自由基聚合（ATRP）的高效催化剂。苯乙烯的聚合速率是在非极性介质中铁介导的ATRP所报道的最高速率之一，与配合物的E1/2电位和ΔEp值有很好的相关性。我们认为，三齿配体的刚性，再加上金属中心周围有足够的空间来容纳一个卤原子，是这些体系具有高效ATRP行为的一个重要因素。
