Abstract

We report the characterization of [Fe(T1Et4iPrIP)(sal)] () (T1Et4iPrIP = tris(1-ethyl-4-isopropyl-imidazolyl)phosphine; sal = salicylate dianion), which serves as a model for substrate-bound salicylate dioxygenase (SDO). Complex crystallizes in the monoclinic space group 2/n with = 10.7853(12) Å, = 16.5060(19) Å, = 21.217(2) Å, = 94.489(2)°, and = 3765.5(7) Å. The structure consists of Fe bonded in distorted square pyramidal geometry ( = 0.32) with two salicylate oxygens and two T1Et4iPrIP nitrogens serving as the base and the apical position occupied by the other ligand nitrogen. [Fe(T1Et4iPrIP)(OTf)] (), the precursor for , catalyzes the cleavage of 1,4-dihydroxy-2-naphthoate in the presence of O. Complex is also capable of cleaving the salicylate aromatic ring in the presence of HO. The progression of this reaction toward product formation involves an Fe-phenoxide species.

摘要

我们报道了[Fe(T1Et4iPrIP)(sal)]（）（T1Et4iPrIP = 三（1-乙基-4-异丙基-咪唑基）膦；sal = 水杨酸二价阴离子）的表征，它作为底物结合的水杨酸双加氧酶（SDO）的模型。配合物以单斜空间群2/n结晶，a = 10.7853(12) Å，b = 16.5060(19) Å，c = 21.217(2) Å，β = 94.489(2)°，V = 3765.5(7) ų。该结构由以扭曲的四方锥几何构型（τ = 0.32）键合的铁组成，两个水杨酸氧原子和两个T1Et4iPrIP氮原子作为底面，另一个配体氮原子占据顶端位置。[Fe(T1Et4iPrIP)(OTf)]（），的前体，在O₂存在下催化1,4-二羟基-2-萘甲酸的裂解。配合物在HO₂存在下也能够裂解水杨酸芳环。该反应向产物形成的进程涉及一种铁-酚盐物种。
