A method is reported for the determination of both the primary and secondary kinetic isotope effects at a reactive center based on staring material reactivities. This allows the determination of the separate KIEs in reactions for which neither produc

The reaction of 2,2,6,6-tetramethylpiperidinyloxy (TEMPO) with t-butyl hydroperoxide, in the presence of catalytic amounts of FeIII yields oxygen. This reaction, which has never been described in the literature so far, led us to envisage a totally ne

By comparing the reactivities of alcohols and alkanes towards TBHP radical oxidation and non-radical Gif oxidation, we bring additional evidence regarding the non-radical nature of Gif chemistry.

Normalized data for cyclooctane and for cyclododecane are compared with cyclohexane as unity. In radical chemistry cyclooctane is 2–3 times more reactive per hydrogen, whereas in Gif chemistry cyclohexane is more reactive than cyclooctane or cyclod

A convenient and high yielding preparation of 2,6-di-t-butyl-1,4-benzoquinone from the iron-catalyzed oxidation of 2,4,6-tri-t-butylphenol with t-butyl hydroperoxide (TBHP) under acidic conditions is reported.

The substitution of saturated hydrocarbons by the anions nitrite, thiocyanate, azide and chloride, using H2O2 and TBHP as oxidants has been shown to depend upon the FeII-FeIV manifold and to involve radical chemistry. As soon as the FeII has been oxi
