Yakura and coworkers have developed bifunctional catalysts bearing TEMPO and iodobenzene moieties (stmctures 110 and 111, Eigure 4.3), which are useful for the environmentally benign oxidation of primary alcohols to carboxylic acids. Reaction of primary alcohols with a catalytic amount of catalyst 111 in the presence of peracetic acid as the terminal oxidant under mild conditions affords the corresponding carboxylic acids in excellent yields [91]. 

Efficient and recyclable bifunctional catalysts bearing silica-supported RuCls and iodoarene moieties have been developed and used for the environmentally benign oxidation of alcohols or alkylarenes at the benzylic position. In the presence of these catalysts, the oxidation of alcohols or alkylbenzenes by Oxone as the stoichiometric oxidant affords the corresponding carbonyl compounds in high yields under mild conditions and convenient work-up. Furthermore, these Si02-supported bifunctional catalysts can be recovered by simple filtration and directly reused (Section 5.5) [100].

In short, we expect the interest in selective, environmentally benign oxidation of alcohols, using both chemo- and biocatalytic methodologies, to continue unabated in the future.
