Description
Summary:In this study, we successfully employed a 19 F‐labeled cyclopalladium probe to achieve simultaneous differentiation and detection of various amines and N‐heterocyclic compounds. This method features a broad detection window, facilitating the discrimination and multi‐component analysis of structural analogs and isomers through the generation of characteristic 19 F NMR signals with distinct chemical shifts. The utility of this approach is demonstrated in monitoring chemical reactions and identifying components in food, beverages, and cosmetics.
