The title piperidine-1-oxoammonium perchlorate I is a stable, nonhygroscopic oxoammonium salt that is easily prepared and can be used for the oxidation of alcs. to ketones or aldehydes in near quant. yields. The reaction is colorimetric, does not require anhydrous conditions, does not involve heavy metals, and can be carried out conveniently. Furthermore, the oxidant can be easily regenerated. The oxidation is somewhat specific in that the relative reactivities of an allyl alc. (geraniol), benzaldehyde, and 1-decanol are about 1001:0.1. The reaction is catalyzed by silica gel.
