Preparation of a carboxylate-binding mononuclear Iron(II) (-)-sparteine complex with structural distortion and its reaction with oxidants

A novel iron complex with a distorted coordination geometry, [Fe-II((-)-sp)(OBz)(2)] (1) ((-)-sp = (-)-sparteine, OBz = benzoate anion), was prepared and structurally characterized by X-ray analysis. The stoichiometric reaction of 1 and mCPBA (m-chloroperbenzoic acid) degraded EtCN to CN- and CH3CHO. In CH2Cl2, a very short-lived intermediate species was generated, exhibiting an intense absorption band at 420 nm (epsilon approximate to 2000 M-1 . cm(-1)) and a weak absorption band at 870 nm (epsilon approximate to 2000 M-1.cm(-1)).
