Reaction of hydroxylated naphtoquinones/antraquinones with pentafluoropyridine [PDF]
SpringerPlus, 2016 In this study, the reaction of pentafluoropyridine with hydroxylated naphtoquinones and hydroxylated antraquinones was investigated under basic conditions in DMF. One or two hydroxyl group in naphtoquinones and antraquinones react with pentafluoropyridine to give mono and di-tetrafluoropyridyl naphtoquinones/antraquinones.

Real-time observation of multi-mode vibronic coherence in pentafluoropyridine [PDF]
The Journal of Chemical Physics, 2017 The ultrafast dynamics of pentafluoropyridine in the 1 1B2 (ππ*) electronic state excited at λpump = 255 nm is investigated by femtosecond time-resolved time-of-flight mass spectrometry and photoelectron imaging spectroscopy. A pronounced, long-lived, and complex periodic modulation of the transient ion yield signal with contributions by four distinct ...
