C(sp 3 )-H oxidation and chlorination catalysed by a bioinspired pincer iron(III) complex.

A pincer iron(III) catalyst for the oxidation and chlorination of C(sp 3 )-H bonds was developed. Oxidation of a diagnostic substrate cis -decalin implies that a long-lived carbon-centred radical is involved. Mechanistic studies suggest that an Fe-oxo species could be responsible for the rate-determining C-H activation step. This report expands the scope of non-heme catalysts for C-H functionalisation.
