Perfluoro(2-methyl-2-pentene) reacts with sodium azide in acetonitrile at -10°C to yield perluoro-(3-azido-2-methyl-2-pentene), which is stable only at low temperature. When the reaction is carried out in the presence of ethanol at the same temperature, stable 5-ethoxy-5-pentafluoroethyl-4,4-bis(trifluorornemyl)-4,5-dihydro-1H-1,2,3- triazole is formed. The reaction in the system acetonitrile-ethanol at 2°C yields ethyl pentafluoropropanimidate and bis(trifluoromethyl)diazomethane. Thermolysis and photolysis of perfluoro-(3-azido-2-methyl-2-pentene) in CCl4, as well as in C6H6, toluene, or pentane, results in fromation of 3-pentafluoroethyl-2,2-bis(trifluoromethyl)-2H-azirine.
