The addition of dianisyl telluride to a GifIV oxidation of adamantane has a marked effect on the ratio of ketone to secondary alcohol formed. This is interpreted as an indication of a second intermediate in the conversion of saturatedhydrocarbons into ketones. This second intermediate is probably an FeIII alkoxide.

Utilization of the GoAggIV system in the presence of sodium azide, sodium nitrite, sodium thiocyanate, sodium disulfide and tetraethylamonium cyanide converts saturated hydrocarbons into the corresponding alkyl azides, nitroalkanes, alkyl thiocyanates, dialkyl disulfides and alkyl cyanides, respectively. Mechanistic studies suggest an Fe-centered ligand coupling reaction pathway.

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
Functionalisation of saturated hydrocarbons. part x.1 a comparative study of chemical and electrochemical processes (gif and gif-orsay systems) in pyridine in acetone and in pyridine-co-solvent mixtures
Six saturatedhydrocarbons (cyclohexane, 3-ethylpentane, methylcyclopentane, - and -decalin and adamantane) were oxidised by the GifIV system (iron catalyst, oxygen, zinc, carboxylic acid) and its electrochemical equivalent (Gif-Orsaysystem). Results obtained using various solvents (pyridine, acetone, pyridine-acetone mixtures) were similar for both systems. Total or partial replacement of pyridine
