Coordination compounds of 3d-metal valerates and benzoates with nicotinamide
摘要:
Complexes of iron(II), cobalt(II), nickel(II), copper(II), and zinc valerates and benzoates with nicotinamide were synthesized. The products were characterized by chemical analysis, IR spectroscopy, diffuse reflection spectroscopy, and thermogravimetry.
Formation of ferricinium ion is the primary step in reactions of ferrocene with t-butyl perbenzoate, benzoyl peroxide, and N-nitrosoacetanilide. Ferrocene is unaffected by treatment with free-radical reagents or arenediazonium salts under experimental conditions precluding formation of ferricinium ion. 1-Cyano-1-methylethyl radicals and benzyl radicals each react with ferricinium ion forming appropriately
A novel iron complex with a distorted coordination geometry, [FeII((−)-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 (ε ≈ 2000 M−1·cm−1) and a weak absorption band at 870 nm (ε ≈ 100 M−1·cm−1).

Results of an experimental study of the influence exerted by the solvent nature on the reaction rate, achieved degree of acid expenditure, selectivity with respect to salts of iron(II) and (III), and phase state of the reaction mixture in a single-stage reaction of iron with benzoic acid and atmospheric oxygen in the presence of a stimulating iodine additive are presented.
