Detection and Identification of Alkenes and Alkynes Using a 19 F-Labeled NMR Probe
Abstract
F NMR signal changes, thereby allowing "separation-free" analysis without requiring complex sample pretreatment. Experimental results demonstrate that the probe can effectively discriminate between terminal and disubstituted alkynes, distinguish structurally similar compounds and regioisomers, and simultaneously identify multiple alkene and alkyne components in mixed samples, showing good anti-interference capability and potential for multiplexed analysis. This method offers a simple, sensitive, and reliable new strategy for the rapid identification and structural analysis of unsaturated compounds in complex matrices.
