Synthesis and molecular structure of a perfluorinated pyridyl carbanion

Reaction of pentafluoropyridine with sodium nitromethanide allowed the isolation and characterisation of the first perfluorinated pyridyl carbanion system, sodium nitrobis(perfluoropyridin-4-yl)methanide, by X-ray crystallography.

The first perfluorinated pyridyl carbanion, sodium nitrobis(perfluoropyridin-4-yl)methanide, to be characterised by X-ray crystallography is reported.Figure optionsDownload as PowerPoint slideHighlights
► Pentafluoropyridine reacts with sodium nitromethanide to give a perfluorinated pyridyl salt.
► First perfluorinated pyridyl carbanion system characterised by X-ray crystallography.
► Most negative charge of the salt is located on the nitro group rather than the pyridine rings.
