Ruthenium comes to its senses : Determining how effectively ruthenium residues are removed from olefin metathesis reactions calls for an alternative evaluation method to ICP‐MS. A fluorescent chemosensor for ruthenium has been developed based on an alkene oxidation reaction (see figure). This fluorescence method has a good selectivity as well as an excellent sensitivity and a 0.32 ppb detection limit. Its streamlined and high‐throughput character is demonstrated by sensing residual Ru in samples containing functionalized organic compounds.
