Modular Synthesis of 9,10-Dihydroacridines through an <i>ortho</i>-C Alkenylation/Hydroarylation Sequence between Anilines and Aryl Alkynes in Hexafluoroisopropanol
precursors typically requires multiple steps. Herein, a modular one-pot synthesis of 9,10-dihydroacridine frameworks is achieved through a reaction sequence featuring a selective ortho-C alkenylation of diarylamines with aryl alkynes followed by an intramolecularhydroarylation of the olefin formed as an intermediate. This transformation was accomplished by virtue of the combination of hexafluoroisopropanol

Sensors and methods for determination of analytes are provided. Analytes including explosives (e.g., RDX or PETN) may be determined by monitoring, for example, a change in an optical signal of a material upon exposure to the analyte. In some embodiments, the analyte and the material may interact via a chemical reaction to form a new emissive species. Embodiments described herein may provide inexpensive sensors with high selectivity and sensitivity.
