2-三氟甲基-1,1,1,3,3,3-六氟丙烷

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

实验步骤: Following the procedure of Example 1, 100 g (0.274 mole) ##STR5## 3.5 g anhydrous KF, 60 g (2.02 mole) trioxane (α-trioxymethylene), 50 mL dimethylformamide and 100 mL dimethylacetamide were heated from 100° C. to 143° C. over a 25 hour period. The cold trap yielded 29.4 g crude product which on GC analysis indicated that 15 g (0.09 mole) was CF3COCF3, 4.4 g (0.027 mole) was (CF3)2C=CH2 and 5.0 g (0.023 mole) was (CF3)3CH. The yields of hexafluoroacetone and hexafluoroisobutylene were 16.4% and 4.9% respectively based on starting hexafluorothioacetone dimer. were heated from 100° C. to 143° C. over a 25 hour period The cold trap yielded 29.4 g crude product which on GC analysis
