1,1,1-trifluoro-5-methylhexane-2,4-dione

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture comprising 213 g (1.17 mol) of 1,1,1-trifluoro-5-methyl-2,4-hexanedione, 242 g (1.64 mol) of ethyl orthoformate and 166 g (1.63 mol) of acetic anhydride, was heated and refluxed for 6 hours. The solvent was distilled off under reduced pressure to obtain 146 g (yield: 67%) of 3-ethoxymethylene-1,1,1-trifluoro-5-methyl-2,4-hexanedione. refluxed for 6 hours The solvent was distilled off under reduced pressure

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
