Kinetics for the recombination of phenyl radicals

The rate constant for the C6H5 + C6H5 recombination reaction has been determined in the temperature range 300-500 K using a laser photolysis/mass spectrometric technique. The result is represented by k1 = (1.39 ± 0.11) × 1013e-(56±36)/T cm3/(mol s). In addition, the rate constant for the C6H5 + C6H5NO association reaction was found to be k4 = (4.90 ± 0.19) × 1012e(34±16)/T cm3/(mol s) by the mass balance of the initial concentration of C6H5 radicals. Using the result of k1, previous kinetic data for C6H5 reactions determined by the conventional relative rate method were reanalyzed.

Reactions of N-nitrosodiphenylamine with Grignard reagents. A convenient synthesis of diaryl- and dialkyl nitroxyls

N-nitrosodiphenylamine reacts with Grignard reagents forming symmetric dialkyl- or diarylhydroxylamines which are quantitatively converted into the corresponding nitroxyls by lead dioxide oxidation.

The reactions of nitrosoarenes with cationic cyclohexadienyl complexes of iron tricarbonyl: an ESR study

The reactions of nitrosoarenes with the (cyclohexadienyl)Fe(CO)3 cation have been investigated by using electron spin resonance spectroscopy.The radicals produced are nitroxides of the type (OC)3Fe(C6H7)(Ar)N-O* but, in some cases, disproportionation and loss of the metal carbonyl fragment leads to the corresponding C6H5(Ar)N-O* radical.With bulky nitrosoarenes, such as C6Me5NO, isomers are observed in which the aryl ring rotation is slow on the ESR time scale.The analogous reactions with the cyclohexadienyl cation derived from the B ring of (ergosteryl acetate)Fe(CO)3 lead to initial attack not at one of the termini of the delocalized system but rather at the central carbon, i.e., at C-7.Subsequent hydrogen migration leads to the (5,7-diene)Fe(CO)3 complex bearing the arylnitroxide at the 7-position.The mechanisms of these reactions are discussed.Key words: nitrosoarenes, iron cations, ESR.
