Photochemistry of halogenocarbon compounds. Part 6. Direct observation of fluorinated azetes

Low temperature photolyses of trifluoro-1,2,3-triazine and the corresponding perfluoro-4,6-di-isopropyl derivative gave clear evidence of azete formation by observing IR spectra and by transference to a mass spectrometer. Evidence for trapping the preformed azetes, with furan, is presented. Only cleavage of perfluorotri-isopropyl-1,2,3-triazine, to alkyne and nitrile was observed on low temperature photolysis.
