Ultrasound promoted facile synthesis of some pentafluoropyridine derivatives at ambient conditions
Ultrasonics Sonochemistry, 2011 Some pentafluoropyridine derivatives have been synthesized by the reaction of pentafluoropyridine with appropriate mono and bidentate nucleophile under ultrasonic irradiation. This new methodology provides good to excellent yields in short reaction times (25-120 min) at room temperature.

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 ...
