Mono and bis hexamethylenetetramine iron(III) chloride, Fe(N C ,H ) CI (I) and Fe(N C ,H ) Cl (II) were synthesized by the reaction of iron(III) chloride and hexamethylenetetramine (HMTA) in chloroform. Chemical analysis and spectral results show the coordination of HMTA to the iron(III). Electronic transition spectra of compound I and I1 were also studied in coordinating and noncoordinatin...

h-point standard addition method (hpsam) was applied for the simultaneous determination of v(v) and fe(iii). the method is based on the complex formation of v(v) and fe(iii) with chromazurol s (cas) in acidic media and in the presence of cetyltrimethylammonium bromide (ctab) as a micellizing agent. acidic media and the presence of a micellar system improve selectivity and sensitivity. fe (iii) ...

a facile and efficient protocol for the synthesis of 1,8-dioxo-octahydroxanthenes has been developed by one-pot knoevenagel condensation, michael addition and cyclodehydration reaction of dimedone (active methylene carbonyl compound) with aromatic aldehydes in the presence of iron (iii) sulfate hydrate as a solid acidic catalyst under solvent-free conditions. various aromatic aldehydes were uti...

     In this study a new simple selective and sensitive spectrophotometric procedure for determination of Fe(III) is described. It is based on the formation of a colored complex between ferric iron and ethyl maltol, a strong and highly selective ligand for Fe(III). After mixing sample and reagent, and incubating at the room temperature, Fe(III)-ethyl maltol complex was extracted with different ...

Iron (III) phosphate catalyzed condensation reaction of aldehydes, 1,3-dicarbonyl compounds and amuniom acetate refluxing ethanol that remains a common theme in current literature.

Bis-(hydroxyamino)triazines (BHTs) constitute a new, general and highly versatile group of tridentate iron(III) chelating agents exhibiting higher affinity to iron(III) than other tridentate iron(III) chelators and superior iron(III) over iron(II) selectivity compared to desferrioxamine-B (DFO), EDTA as well as other tridentate ligands.

High-spin iron(III) iodosylarene complexes bearing an N-methylated cyclam ligand are synthesized and characterized using various spectroscopic methods. The nonheme high-spin iron(III) iodosylarene intermediates are highly reactive oxidants capable of activating strong C-H bonds of alkanes; the reactivity of the iron(III) iodosylarene intermediates is much greater than that of the corresponding ...
