A series of monomeric chloroiron(III) complexes with the quadridentate or quinquedentate Schiff bases such as N,N'-disalicylideneethylenediamine or bisamine react with superoxide ions, O2-, in dimethyl sulfoxide to give the corresponding μ-oxo dimers.The polymeric chloroiron(III) complexes with the polymeric (oligomeric) Schiff bases derived from 5,5'-methylenedisalicylaldehyde and triamines react with O2- in dimethyl sulfoxide to give the oxygenated complexes, probably dioxygen adducts, FeIII-O2-.This is suggested by the absorption spectra and the polarographic measurements.

The kinetics and mechanism of the reduction of the μ-adi-di[N,N′- bis{salicylideneethylenediaminatoiron(III)}] complex, [Fe2adi], by dithionate ion, S2O6 2-, have been investigated in aqueous perchloric acid at 29 C, I = 0.05 mol dm-3 (NaClO 4) and [H+] = 5.0 × 10-3 mol dm -3. Spectrophotometric titrations indicated that one mole of the reductant was oxidized per mole of oxidant. Kinetic profiles indicated first-order rate with respect to [Fe2adi] but zeroth-order dependence on [S2O6 2-]. The rate of reaction increased with increase in [H+], decreased with increased dielectric constant, but was invariant to changes in ionic strength of the medium. Addition of small amounts of AcO- and Mg2+ ions did not catalyse the reaction. A least-squares fit of rate against [H+]2 was linear (r 2 = 0.984) without intercept. The reaction was analysed on the basis of a proton-coupled outer-sphere electron transfer mechanism.

Paragraph 0022-0024, (2017/09/29)
PROBLEM TO BE SOLVED: To provide a production method of an organic compound crystal, with which a crystal structure of the organic compound crystal can be controlled. SOLUTION: A production method of an organic compound crystal including: a synthesis step to synthesize an organic compound represented by A-B-C (A and C are cyclic structures identical to or different from each other, and B is a connector to connect A and C); a reprecipitation step to reprecipitate the A-B-C in a solvent after the synthesis; and a recrystallization step to recrystallize a precipitate recovered in the reprecipitation step is disclosed in this application. Each of A and C is an organometallic complex comprising heterocycles coordination-bonded to a metal, and A and C are connected to each other via an electron donor (B).

μ-Oxo-Dinuclear-Iron(III)-Catalyzed O-Selective Acylation of Aliphatic and Aromatic Amino Alcohols and Transesterification of Tertiary Alcohols
Horikawa, Rikiya,Fujimoto, Chika,Yazaki, Ryo,Ohshima, Takashi
, p. 12278 - 12281 (2016/08/24)
A highly chemoselective and reactive μ-oxo-dinuclear iron(III) salen catalyst for transesterification was developed. The developed iron complex catalyzed acylation of aliphatic amino alcohols with nearly perfect O-selectivity, even when using activated esters, for which chemoselectivity is more difficult to control. In addition, O-selective transesterification of aromatic amino alcohols was achieved for the first time. The high activity of the iron complex enabled the use of sterically congested tertiary alcohols, including unprecedented tert-butanol.
