The use of tert-butyl hydroperoxide as an oxidant in Gif-type systems (GoAggIV and GoAgfV) catalyzed by various Fe(III) species is examined. Regioselectivity studids of these systems have revealed several characteristics similar to those observed for other prdviously reported Gif-type reactions. A common rdaction pathway for the GoAggIV and GoAggV oxidation systems and other Gif-type reactions (from

The hydroxylation of cycloalkanes at 25 °C by the syringe pump addition of tert-alkyl hydroperoxides (10 and 1 equiv based on catalyst) to deoxygenated acetonitrile containing cycloalkanes (0.64 M) and 0.61 mM of the catalyst, [FeIII2O(TPA)2(H2O)2]4+, is demonstrated to be a reaction which involves freely diffusing cycloalkyl radicals, i.e., free alkyl radicals.

The oxidation of cyclooctane using tert-alkyl hydroperoxides under GoAggV conditions has been examined using selected alkyl hydroperoxides as mechanistic probes. The results indicate that the products are formed by alkoxyl radical-induced reactions, there being no need to invoke any chemistry involving high valent iron-oxo species.

GoAggIV chemistry (Fe (III) species, tert-butyl hydroperoxide in a mixture of pyridine and acetic acid) in the presence of LiCl can transform saturated hydrocarbons efficiently into the corresponding alkyl chlorides. The transformation into monosubstituted alkyl derivatives by “ionic trapping” reagents arising from the interception of the first intermediate of the system supports the presence of a

The Fe(III)-catalyzed ketonization of saturatedhydrocarbons by tert-butyl hydroperoxide (TBHP) in pyridine-acetic acid or acetonitrile solution follows the reaction pathway alkane → alkyl hydroperoxide → ketone or alcohol. Dioxygen (O2) is the precursor of the oxygen atoms in the alkyl hydroperoxide, the alcohol, and the ketone.
