[Fe(salphen)Cl]的晶体结构(H2salphen=N,N′-(1 R,2 R)-1,2-二苯基乙烯双(水杨醛亚胺))的研究表明,Schiff碱配体上的大取代基引起的空间位阻效应使配合物的反应活性发生了剧烈的变化;氯铁(III)络合物在碱化时产生μ-氧代络合物的典型二聚化被抑制,导致高产率地转化为氢氧化物盐。
Crystal structure of [Fe(salphen)Cl] (H2salphen=N,N′-(1R,2R)-1,2-diphenylethylenebis(salicylideneimine)) reveals that a steric effect induced by the bulky substituent on the Schiff base ligand brings about drastic changes in the reactivity of the complex; the typical dimerization of the chloroiron(III) complex upon basification to yield μ-oxo complexes are suppressed, resulting in the high-yielding conversion to a hydroxide salt.
