General description
The reactions of pentafluoropyridine with cobalt(0) complex, Co(PMe3)4 was investigated.
Pentafluoropyridine is a fluorinated building block for the synthesis of polysubstituted pyridine derivatives.
Pentafluoropyridine is a fluorinated building block for the synthesis of polysubstituted pyridine derivatives.
Application
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.

The reactions of pentafluoropyridine C5NF5, hexafluorobenzene C6F6, and perfluoronaphthalene C10F8 with cobalt(0) complex, Co(PMe3)4, were investigated. The Co(I) complexes (4-C5NF4)Co(PMe3)3 (1), (C6F5)Co(PMe3)3 (2), (C10F7)Co(PMe3)3 (3), (4-C5NF4)Co(PMe3)4 (4) and (C10F7)Co(PMe3)4 (6) were obtained by selective activation of the C–F bonds. The

The structures of the three para-substituted halotetrafluoropyridines with chlorine, bromine, and iodine have been determined in the solid state (X-ray diffraction). The structures of these compounds and that of pentafluoropyridine were also determined in the gas phase (electron diffraction). Structures
