Dechlorination reactions at sp(2) C-Cl bonds by a pentaphosphino zero-valent iron (ZVI) complex are proposed to follow an oxidative addition, β-Cl-elimination pathway en route to iron-chloride, iron-hydride and iron-acetylide products, the distribution being dependent on the nature of alkyne produced.

Reaction of different combinations of aryl(dihalo)boranes and trialkylsilyl iron metallates, a route previously used to prepare a terminal iron arylborylene complex, is found to lead to three distinct new reaction outcomes, including unselective decomposition, an inert iron(II) (boryl)(silyl) complex, and a dinuclear bis(μ-silylene) complex. The latter result is to our knowledge the first examp...

A sensitive and simultaneous spectrophotometric flow injection method for the determination of vanadium(IV) and vanadium(V) is proposed. The method is based on the effect of ligands such as 2,4,6-tris(2-pyridyl)-1,3,5-triazine (TPTZ) and diphosphate on the conditional redox potential of iron(III)/iron(II) system. A four-channel flow system is assembled. In this flow system, diluted hydrochloric...

This communication reports the use of a gel filtration technique and radioactive iron for rapid determination of protein-iron binding in complex mixtures. Many methods have been used to investigate the characteristics of iron binding by mammalian serum. Calorimetric techniques have been used to measure the iron-binding capacities of whole seral. Electrophoretic2y3 and precipitation41s methods, ...
