Pd(II), Pt(II), and Au(III) ions which strongly prefer square planar coordination geometry in their d8 configuration, but also the Ag(II) ion in its d9 configuration, are practically devoid of any coordination chemistry in their porphyrin complexes, apart from intermediates that may be observed during metalloporphyrin formation and a few reactions which have already been discussed in previous reviews [7, 8]. [Pg.44]

Metalloporphyrin formation. Our earlier study of metal ion incorporation by TPP was carried out in a benzene in water micro-emulsion (ME) stabilized by cyclohexanol and a few different surfactants (.8). The Influence of Lewis bases, quinoline in particular, was studied in the ME system containing (anionic) sodium cetyl sulfate (SCS). For reasons to be discussed below, it was... [Pg.180]

The microemulsion components, particularly the nature of the oil, has been shown to have a dramatic effect on the interaction of metal ions in the microdroplet Interfaclal region. In particular, the change from benzene to mineral oil causes a change in the quinoline dependence of the rate of metalloporphyrin formation and a 0.9 volt shift in copper(II) half- ave potential. The... [Pg.193]

Kinetic Evidence for Short-Lived Intermediates in Metalloporphyrin Formation... [Pg.221]

A number of studies on metalloporphyrin formation have been reported over 20 years, as a result of the important role of metalloporphyrins in biological systems. The general mechanism for the metalation of porphyrins was first proposed 1 Hambright emd Chock, and has been reviewed from time to time by Hambright, Lavallee. Schneider, and Tanaka. The rate of metalloporphyrin formation is several orders of magnitude slower than that of the... [Pg.221]
