We review structure–catalytic property relationships for MOF materials used in the direct oxidation of light alkanes, focusing specifically on the elucidation of active site structures and probes for reaction mechanisms.
A new Fe(iii) coordination compound of o-vanillin acts as an efficient catalyst for alkane oxidation and features long-range exchange coupling between metal centres.
Nickel(ii) complexes with oxazoline-based tripodal ligands are efficient catalysts for alkane oxidation, and reaction rates and oxidizing position selectivity are controlled by the structural properties of the substituent groups on the ligands.
The specific ionic liquid [TBA][Pic]-stabilized vanadium oxo-clusters exist in the form of a trimer and a dimer and are highly active for catalyzing C–H bond oxidation with H2O2 as an oxidant.
