Abstract

A mononuclear Fe(II) complex bearing 1-aminocyclopropane-1-carboxylic acid (ACCH) was synthesized and characterized. X-ray crystallography demonstrated that ACC binds to the Fe(II) ion in a bidentate mode constituting the first structural mimic of the expected binding of ACC to the Fe(II) center of the ethylene forming enzyme ACC-oxidase (ACCO). [Fe(BPMEN)ACC]SbF6 also constitutes a functional biomimetic complex of ACCO, as it reacts with hydrogen peroxide producing ethylene.

摘要

合成并表征了一种含有1-氨基环丙烷-1-羧酸（ACCH）的单核铁（II）配合物。X射线晶体学表明，ACC以双齿模式与Fe（II）离子结合，构成了ACC与乙烯形成酶ACC氧化酶（ACCO）的Fe（II）中心预期结合的首个结构模拟物。[Fe（BPMEN）ACC]SbF6也构成了ACCO的功能性仿生配合物，因为它与过氧化氢反应生成乙烯。
