The product from the fluorination of pyridine by KCoF4 at ca. 220° contains eleven fluoropyridines, two fluoro-2-azahex-enes, three azahexa- dienes, and two fluoro-N-methylpyrrolidines, besides an azacyclohexa-1,3- diene. Four products were isolated from a fluorination of pyridine by CoF3 at ca. 150°, a 2-azahexene, two N-methylpyrrolidines, and 4H-nona- fluoropiperidine.
在大约220°C的条件下,通过KCoF 4氟化吡啶的产物,除了氮杂环己基1,3-二烯外,还包含11个氟吡啶,2个氟-2-氮杂双烯,3个氮杂己二烯和2个氟-N-甲基吡咯烷。通过在约150°C的CoF 3氟化,从吡啶中分离出四种产物,分别是2-氮杂双烯,两个N-甲基吡咯烷和4H-壬基-氟哌啶。
