“…Moreover, the affinity of Fe(Salen)Cl for the oxygen molecule and the capability to form oxo-complexes is similar to what observed for Fe III porphyrin derivatives [21,22] and for all the transition metal-Salen complexes showing the property to cleave DNA [11][12][13][14][15][16][17][18][19].…”

“…It is known that, depending on the solvent used to recrystallize it, Fe(Salen)Cl can be obtained as a monomer [21,35] or as a dimer [36]. In the dimeric structure, the iron atoms of two square pyramidal structures are connected by two oxygen bridges [36], filling the sixth coordination sites of the metal in a distorted octahedral coordination geometry.…”

“…Some structural and chemical similarities between Fe III (Salen)Cl and Fe III porphyrins exist [21,22]. As in Fe III porphyrins, the iron atom of Fe III (Salen)Cl is pentacoordinated in a pyramidal geometry, with the tetradentate Salen ligand in a square planar coordination, the fifth chloride ligand in an apical position and an open sixth coordination site.…”

“…As in Fe III porphyrins, the iron atom of Fe III (Salen)Cl is pentacoordinated in a pyramidal geometry, with the tetradentate Salen ligand in a square planar coordination, the fifth chloride ligand in an apical position and an open sixth coordination site. Although the Salen tetradentate ligand consists of two nitrogen and two oxygen, rather than four nitrogen donor atoms [21], Salen ligands have been shown to form complexes that mimic porphyrin chemistry [23]. Fe III (Salen), analogously to Fe III porphyrins, shows a catalytic activity toward the bland oxidation of hydrocarbons [21] and undergoes electron transfer reactions [22], mimicking the catalytic functions of peroxidases [22].…”

In the present study, at first, 2,4-Dihydroxy Salophen (2,4-DHS), has been synthesized by combination of 1, 2-diaminobenzene and 2,4-dihydroxybenzaldehyde in a solvent system. This ligand containing meta-quinone functional groups were characterized using UV-Vis and IR spectroscopies. Subsequently, the interaction between native calf thymus deoxyribonucleic acid (ct-DNA) and 2,4-DHS, was investigated in 10 mM Tris/HCl buffer solution, pH 7.2, using UV-visible absorption and fluorescence spectroscopies, thermal denaturation technique and viscosity measurements. From spectrophotometric titration experiments, the binding constant of 2,4-DHS with ct-DNA was found to be (1.1 ± 0.

In this article, catalyst systems for homogeneous epoxidation are reviewed with an emphasis on reaction elements that are of foremost interest to synthetic chemists: catalyst systems, substrate scope, and selectivity. General mechanisms and reaction conditions for each catalyst system are discussed followed by more detailed summaries of the epoxidation of specific classes of olefins: unfunctionalized terminal olefins, cis‐disubstituted, trans‐disubstituted, tri‐ and tetrasubstituted olefins, functionalized olefins including allylic alcohols, and electron‐deficient olefins. Major classes of catalysts addressed are early transition metal‐peroxo forming catalysts (inclusive of the Sharpless titanium tartrate catalyst for the asymmetric epoxidation of allylic alcohols and MTO), metal‐oxo forming catalysts (such as metalloporphyrin and Jacobsen/Katsuki salen catalysts), dioxirane and oxaziridine catalysts, Lewis acid and lanthanide catalysts, phase‐transfer and polyamino acid catalysts, and finally sulfur ylide catalysts for the formation of epoxides from aldehydes. Dedicated to Professor K. Barry Sharpless on the occasion of his 60th birthday.
