Electrochemical study cobalt complex

The study just described is in accordance with the observation that electrochemical reduction of the (highly conjugated) phthalocyanine (5) complex of Mn(n) also gives no evidence for the formation of a Mn(i) species (in contrast to the corresponding iron and cobalt complexes which, on reduction, yield Fe(i) and Co(i) products) (Lever, Minor Wilshire, 1981). 

The cobalt-59 NMR spectra of various Co(R2Dtc)3 complexes and of Co(RXant)3 have been reported. For B0 =450 cm-1 a linear correlation between the resonance frequency (p/) and the Tig - Aig absorption maximum is observed (430). In an electrochemical study, Toropova et al. (592) reported on the catalytic liberation of hydrogen in solutions of Co(R2 Dtc)2 complexes R2 = (hydroxyethyl)2, //-hydroxyethyl, carboxymethyl, etc.). The following mechanism was proposed for this very interesting reaction ...

Scheme 7-24 shows a series of ferrocenyl-cobalt complexes, the electrochemical behavior of which has been accurately studied. 

For the investigation of interaction mechanism of some compounds as metal coordination complexes with DNA, Bard et al. [76] reported comprehensive electrochemical studies using cobalt/ferrum phenanthroline or cobalt/ferrum bipyridine. In that paper, they evaluated limiting shifts and binding constants of mediator compounds by cyclic voltammetry in the absence and presence of DNA in solution phase experiments. As a result of their report, they found those forms (oxidized or reduced form) of mediator compounds which bind to the DNA molecule with a high affinity.

Ferrocene was the first organometallic guest incorporated and numerous spectroscopic and electrochemical studies have been performed on ferrocene, substituted ferrocene, and related metallocene (e.g. cobaltocene) inclusion complexes (444-469]. Half-sandwich cyclopentadienyl- and benzene-metal carbonyl complexes have also been studied quite extensively [470-479] as have // -allyl metal (palladium) complexes [480], diene metal (rhodium) complexes [481-484], acetylene cobalt carbonyl cluster complexes [485], and complexes with metal carbonyls, e.g. Fe(CO)5, Mn2(CO)io, and CoNO(CO)3 [485a]. 

Cyclic voltammetry studies of borabenzene cobalt complexes, (borinato)-cyclopentadienyliron, and bis(borinato) complexes of iron, chromium, and vanadium have appeared. The electrochemical behaviour and e.s.r. spectroscopy of heterocyclic organoboron compounds (60) have been studied. ...
