What is Pentafluoropyridine?
Chemical properties
CLEAR COLOURLESS LIQUID
The Uses of Pentafluoropyridine
Pentafluoropyridine was used in the preparation of η2-C,C coordinated pentafluoropyridine complex. It was also used in the preparation of polyfluorinated coupling products via Pd(0)-catalyzed cross-coupling reaction with diarylzinc compounds. It was also used as derivatizing reagent in the sensitive GC-MS method for determination of the four endocrine disrupting chemicals.
General Description
The reactions of pentafluoropyridine with cobalt(0) complex, Co(PMe3)4 was investigated.
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.]
