Abstract

Selective C[BOND]H oxidation: A novel class of PNNP–RuII complexes is prepared and characterized. These complexes are air stable and easy to handle and show significant catalytic activity in the direct C[BOND]H oxidation of aryl alkanes by using tert-butylhydroperoxide as the reoxidant. Several functionalized ketones are prepared, which exemplifies the synthetically useful functional group tolerance of this method.
