3,3,3-三氟-2,2-二甲基丙腈

反应条件: temp:200.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 3,3,3-trifluoro-2,2-dimethyl-propionamide (Stage 44.4) (121.2 mmol) and phosphorus pentoxide (121.2 mmol) was slowly heated to 200° C. and the resulting distillate collected. The title compound was obtained as a colorless liquid.

反应条件: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 3,3,3-Trifluoro-2,2-dimethyl-propionitrile (Stage 44.3) (12.40 mmol) was added to a solution of sodium methoxide (freshly prepared from 48.40 mmol sodium metal and 102 mL MeOH) at rt. After 4 h, acetic acid (48.40 mmol) and then NH4Cl (14.88 mmol) were slowly added and the reaction mixture was then heated to 70° C. for 40 h. After concentrating (40° C., 100 mbar) the reaction mixture, the residue was suspended in acetone, filtered and dried under vacuum to afford the title compound as a white solid. ESI-MS: [M+H]+ 155. After concentrating (40° C., 100 mbar) the reaction mixture filtered dried under vacuum
