Contamination of active pharmaceutical ingredients and healthcare products with oxidized forms of palladium and platinum are important problems. We report a convenient fluorogenic probe based on the catalyzed aromatic Claisen rearrangement capable of detecting Pd II and Pt IV . Using this probe, we can fluorescently detect Pd II in functionalized organic compounds and Pt IV in Pt 0 -water without sample pretreatment. This method may find broad applications in the pharmaceutical industry, the environment, and Pd/Pt quality control.
