perfluoro-5-azanon-4-ene with a range of bidentate nitrogen nucleophiles (urea, acet-, benz-, 4-nitrobenz-amidine hydrochloride, 2-aminopyridine, 2-aminobenzimidazole, guanidine) in the presence of Et3N or KOH effectively provided partially fluorinated heterocycles of pyrimidine, 2H-pyrido[1,2-a]pyrimidine and [1,3,5]triazine derivatives. The structure of 2-pentafluoroethyl-3-trifluoromethyl-pyrido[1,2-a]pyrimidin-4-one
全氟-2-甲基戊-2-ena或全氟-5-氮杂-4-烯与一系列双齿氮亲核试剂的反应(脲,盐酸,乙酰,苯,4-硝基苯-盐酸盐,2-氨基吡啶,2-氨基苯并咪唑,胍)在Et 3 N或KOH的存在下可有效地提供嘧啶,2H-吡啶并[1,2-a]嘧啶和[1,3,5]三嗪衍生物的部分氟化杂环。通过X射线晶体学分析进一步证实了2-五氟乙基-3-三氟甲基-吡啶并[1,2-a]嘧啶-4-酮的结构。
