✦ Synopsis

The oxidation of 3-ethylpentane under Gifiv (and GoAggR) conditions affords, as major product, 3-acetylpentane and not diethylketone as previously mported. The discrepancy is explained by radical chain autoxidation in presence of a weak tertiary C-H bond The selective activation of saturated hydrocarbons is a topic of curtent interestt One approach involves porphyrin models of P450 enzymes.2 There is considerable agreement that in these systems an iron-oxo species is present which behaves like an alkoxyl radical.3 As a result the selectivity order is tett.> sec.> prim.

We have adopted a different approach using Gif type systems. These have the interesting property of
