化学性质

属性熔点66-68°C描述产品介绍2,3,5,6-Tetrafluoro-4-pyridinecarbonitrile is a perfluorinated heteroaromatic compound. 2,3,5,6-Tetrafluoro-4-pyridinecarbonitrile (tetrafluoro-4-cyanopyridine) reacts with 1,3-dicarbonyl systems to yield the corresponding [5,6]-ring fused furo derivatives. 2,3,5,6-Tetrafluoro-4-pyridinecarbonitrile (4-cyanotetrafluoropyridine) reacts with amidines to yield [6,6]-fused pyrimidinopyridine system via nucleophilic substitution at the C-3 position of the pyridine ring followed by intramolecular cyclization onto the pendant cyano group.Reaction of 2,3,5,6-tetrafluoro-4-pyridinecarbonitrile (4-cyanotetrafluoropyridine) with sulfur centred nucleophiles has been reported别名2,3,5,6-四氟-4-吡啶甲腈;2,3,5,6-四氟-4-氰基吡啶;2，3，5，6-tetrafluoro-4-pyridine-carbonitrile;2,3,5,6-Tetrafluoro-4-Pyridinecarbonitrile; 2,3,5,6-Tetrafluoroisonicotinonitrile应用2,3,5,6-Tetrafluoro-4-pyridinecarbonitrile may be used in the preparation of 2-anilino-3,5,6-trifluoroisonicotinonitrile-----------------------
