- Reactions of perfluoro(2-methylpent-2-ene) and perfluoro(5-azanon-4-ene) with primary amines containing a 2,6-di-tert-butylphenol fragment
-
Reactions of perfluoro(2-methylpent-2-ene) and perfluoro(5-azanon-4-ene) with 4-(2-aminoethyl)-2,6-di-tert-butylphenol and 4-(3-aminopropyl)-2,6-di-tert- butylphenol in acetonitrile in the presence of triethylamine gave the corresponding azetidine, 1,2-dihydroazete, and 1,2-dihydro-1,3-diazete derivatives, respectively. The reaction mechanisms, role of triethylamine, and factors affecting the intramolecular nucleophilic cyclization process are discussed.

- Synthesis of nitrogen-containing heterocyclic compounds using perfluoro-2-methylpent-2-ene and perfluoro-5-azanon-4-ene
-
Reactions of perfluoro-2-methylpent-2-ena or 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 was further confirmed by the X-ray crystallographic analysis.
