Perfluoro-2-methylpent-2-ene and perfluoro-5-azanon-4-ene react with guanid
ine hydrochloride in the presence of triethylamine to give 2-amino-6-fluoro
-4-pentafluoroethyl-5-trifluoromethylpyrimidine and 2-amino-4,6-bis(heptafl
uoropropyl)-1,3,5-triazine, respectively. The structure of the former produ
ct was confirmed by X-ray diffraction analysis.
