Gas-phase deuterium exchange of fluorenes, furans, and thiophenes in the inlet system of a gas chromatograph/mass spectrometer
摘要:
Reaction columns containing a packing of KOD or D3PO4 in a stationary liquid phase on a support as components in a gas chromatograph/mass spectrometer were shown to provide selective basic H/D exchange of fluorenes and furans and acidic H/D exchange of thiophenes under gas-phase conditions. Such columns were proposed for use in the study of fragmentation mechanisms and establishment of the position of substituents in the ring.
