Enhancement of Rates of Reaction using Neutral Water/Organic Microemulsions as Solvent Media

Relative to the rate constants for reactions in aqueous solutions the rate constants for reactions involving (i) Fe(phen)32+ (phen = 1,10-phenanthroline), (ii) Fe(5-NO2phen)32+, (iii) 2,4-dinitrochlorobenzene, and (iv) crystal violet with either hydroxide or cyanide ions are increased markedly when two water/organic microemulsions formed from liquid components are used as reaction media; a similar though less significant change is observed in the related rates of aquation (hydrolysis).

Resonance Raman Investigation of the Electronic Transitions of some Iron(II) and Copper(II) α-Di-imine Complexes

The electronic, i.r., Raman, and resonance Raman spectra of (phen = 1,10-phenanthroline), (bq = 2,2'-biquinolyl), and 2 (bipy = 2,2'-bipyridyl) have been studied.Excitation within the contours of the strong visible charge-transfer bands in the electronic spectra complexes leads to the resonance enhancement of many of the a1 modes of the α-di-imine ligands.The electronic shoulders (present for all three complexes) have their origin in vibronic coupling for 2 and .The electronic side-band for , however, arises from a second electronic transition.The presence of more than one ν(CN) mode in the Raman spectrum of dissolved in 1 mol dm-3 H2SO4 has been explained in terms of protonation of the phenanthroline ligand.

Ligand effects on the reduction of iron(III) complexes by alkyl radicals. Formation of alkyl isocyanides and chlorides from cyanoiron(III) and chloroiron(III) species

The reduction of the cyanoiron(III) complex (NC)2Fe(phen)2+ by various alkyl radicals occurs readily by addition to the cyanide ligand to form an alkyl isocyanide coordinated to iron(II). The infrared and electronic spectra of analogous cyanoiron(II) and (alkyl isocyanide)iron(II) complexes are compared in the series: (CH3NC)2Fe(phen)22+, (CH3NC)(NC)Fe(phen)2+, (NC)2Fe(phen)2. Electron-rich alkyl radicals such as tert-butyl also reduce (NC)2Fe(phen)2+ by an electron-transfer process which affords carbonium ion byproducts. For a particular alkyl radical, the competition between radical addition and electron transfer can be qualitatively related to its ionization potential. Various alkyl radicals also react readily with two series of chloroiron(III) complexes, tetrachloroferrate (III) and trichloroiron(III), to afford the reduced chloroiron(II) species and the corresponding alkyl chloride in essentially quantitative yield. The rates of chlorine atom transfer to alkyl radicals are measured by the competition method using BrCCl3 as a bromine atom donor. The divergent trends in the reactivity pattern of alkyl radicals with tetrachloroferrate(III) and trichloroiron(III) are discussed in terms of FeCL4- and FeCl2+, respectively, as the active chloroiron(III) species in acetonitrile solutions. The various pathways for the reduction of different iron(III) complexes by alkyl radicals are presented in the context of their reduction potentials.
