Pentafluoropyridine(Cas 700-16-3) Usage
|
Synthesis |
Historically, potassium fluoride has been? used with solvents to perform the Halex reaction and Finger and Kruse established the? use of polar aprotic solvents in the Halex reaction, with DMSO and DMF being used for the conversion of pentachloropyridine to pentafluoropyridine. |
|
Purification Methods |
Distil it through a concentric tube column; it has in cyclohexane at 256.8nm. [Chambers et al. J Chem Soc 3573 1964, NMR: Bell et al. J Fluorine Chem 1 51 1971.] The hexafluoroantimonate has m 98-102o(dec) after crystallisation from liquid SO2. [Beilstein 20/5 V 401.] |
|
General Description |
The reactions of pentafluoropyridine with cobalt(0) complex, Co(PMe3)4 was investigated. |
