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.

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 ...
PhN=N-N(CH 2) 5 + 2 HF → PhF + N 2 + [(CH 2) 5 NH 2]F. Historical note: in Wallach's era, the element fluorine was symbolized with "Fl". Thus, his procedure is subtitled "Fluorbenzol, C 6 H 5 Fl". [1] On the laboratory scale, PhF is prepared by the thermal decomposition of the benzenediazonium tetrafluoroborate: PhN 2 BF 4 → PhF + BF 3 + N 2
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
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.
Methyl trifluoromethanesulfonate, also commonly called methyl triflate and abbreviated MeOTf, is the organic compound with the formula CF 3 SO 2 OCH 3. It is a colourless liquid which finds use in organic chemistry as a powerful methylating agent. [2] The compound is closely related to methyl fluorosulfonate (FSO 2 OCH 3).
tert-Butyldimethylsilyl chloride is an organosilicon compound with the formula (Me 3 C)Me 2 SiCl (Me = CH 3). It is commonly abbreviated as TBSCl or TBDMSCl. It is a chlorosilane containing two methyl groups and a tert-butyl group. As such it is more bulky that trimethylsilyl chloride. It is a colorless or white solid that is soluble in many ...
Diethylbenzene is used in a mixture with methyl and/or ethyl biphenyls as a low temperature heat transfer fluid. [2] Diethylbenzene is dehydrogenated to give divinylbenzene (DVB): C 6 H 4 (C 2 H 5) 2 → C 6 H 4 (C 2 H 3) 2 + 2 H 2. DVB is used in the production of crosslinked polystyrene. [3]
