The oxidizing agent Ce(IV)[SiO.sub.2] is prepared by coating silica gel with ceric ammonium nitrate and is used to oxidize hydroquinones to their corresponding 1,4-benzoquinone. Analytical results from [H-NMR.sub.1] spectroscopy, including detection limits, will be presented to demonstrate that heterogeneous oxidation only occurs when Ce(IV) is supported on the surface of silica gel, and is not promoted by the individual components of this solid-supported reagent either se parately or when physically mixed.
