Tautomers are constitutional isomers that interconvert into each other by an exchange reaction, most commonly a proton transfer. Such two isomers can for example be a ketone and an enol. Read More.

In the 19F NMR spectrum of DCBTF, we can observe the singlet resonance of the trifluoromethyl fragment at δ = −63.07 ppm. While it might not jump into your eye at first glance, please note that the carbon satellites are not centered at the "main signal", which is what we are used to from 1H NMR spectra. Read more
