2,2,3,3-tetrafluoro-3-iodopropanenitrile

反应条件: temp:140.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 150 g of fine powder of ICF2CF2CONH2 and 235 g of P2O5 was heated at 130 to 150° C., during which time volatiles were distilled out. Final volatiles were collected in a -78° C. trap at 26.6 kPa. A total of 125.3 g of crude product was obtained, 95% pure by GC. Redistillation gave pure product, bp 60-61° C. 19F NMR: -63.3 (t, J=10.4 Hz, 2F), -100.5 (t, J=10.4 Hz, 2F). IR(neat): 2264 (w), 1235 (s), 1196 (s), 1172 (s), 1146 (s), 1089 (s), 1065 (s), 893 (s). were distilled out Final volatiles were collected in a -78° C. trap at 26.6 kPa
