The title compound was synthesized via visible-light-induced radical denitrogenative trifluoromethylation of the corresponding vinyl azide and Cs2CO3-mediated defluorinative cyclization of the resultant azine. Sodium trifluoromethanesulfinate was used as a precursor of CF3 radicals, while graphitic carbon nitride (g-C3N4) acted as an environmentally friendly, cheap, and efficient heterogeneous photocatalyst. The structure of the synthesized compound was confirmed by H-1, C-13, F-19-NMR, IR spectroscopy, and mass spectrometry.
In this work, the title compound was synthesized via the visible-light-induced radical denitrogenative trifluoromethylation of the corresponding vinyl azide followed by Cs2CO3-mediated defluorinative cyclization of the resultant azine. The widely available sodium trifluoromethanesulfinate is used as a precursor of CF3 radicals, while graphitic carbon nitride (g-C3N4) is employed as an environmentally friendly, cheap, and efficient heterogeneous photocatalyst. The structure of the synthesized compound was established by H-1, C-13, F-19-NMR, IR spectroscopy, and mass-spectrometry.
