Synthesis and characterization of [Fe(BPMEN)ACC]SbF₆: a structural and functional mimic of ACC-oxidase

Dalton Trans. 2015 Apr 7;44(13):5966-8. doi: 10.1039/c5dt00347d.

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.
