Abstract:
In CFCl3, aziridines react with F2(6 %/N2, 20°C), COF2 (20 %/N2, 40°C) and CF3OF [1] (20 %/N2, 40°C).Substitution products are obtained : l-(aziridine)carbonyl fluorides and l-Fluoroaziridines In (Et)2O, aziridines react with COF2 (20 %/N2, 10°C) and we have the carbonyl fluorides . Products IV can be thermally decomposed into β fluoro isocyanates.In CFCl3, N substituted aziridines react with F2(6%/N2, 20°C) and with CF3OF [2] (20%/N2, 40°C). No reaction is observed with COF2in our conditions (5% to 25%/N2, 80°C to + 40°C).Addition products are obtained : N Fluoro amines β fluorinated , N Fluoro and NN difluoro amines β trifluoro methoxylated and .with R = SO2Ø, COØNO2, Cl.
