1,2-Difluorobenzene, also known as DFB, is an aromatic compound with formula C 6 H 4 F 2. This colorless flammable liquid is a solvent used in the electrochemical studies of transition metal complexes. Compared to most conventional halogenated aliphatic and aromatic solvents, it possesses an exceptionally high dielectric constant (ε 0 = 13.8 ...
Fluorobenzenes are a group of aryl fluorides/halobenzenes consisting of one or more fluorine atoms as substituents on a benzene core. They have the formula C 6 H 6–n F n, where n = 1–6 is the number of fluorine atoms.
Structure of [(C 5 Me 5) 2 Ti(FC 6 H 5)] +, a coordination complex of fluorobenzene.. PhF is a useful solvent for highly reactive species. Its melting point at -44 °C is lower than that of benzene.

1,2-Dichlorobenzene, or orthodichlorobenzene (ODCB), is an aryl chloride and isomer of dichlorobenzene with the formula C 6 H 4 Cl 2.This colourless liquid is poorly soluble in water but miscible with most organic solvents.
19 F NMR chemical shifts in the literature vary strongly, commonly by over 1 ppm, even within the same solvent. [5] Although the reference compound for 19 F NMR spectroscopy, neat CFCl 3 (0 ppm), [6] has been used since the 1950s, [7] clear instructions on how to measure and deploy it in routine measurements were not present until recently.
