Trifluoroacetate → Hexafluoroacetylacetone

Participants

Reaction Steps

In view of the above circumstances, the present inventors have made extensive researches and resultantly found that: it is possible to form a 1,1,1,5,5,5-hexafluoroacetylacetone hydrate by reacting a 3,3,3-trifluoropropynyl metal with a trifluoroacetate and then bringing the resulting reaction mixture (A), in which at least 1,1,1,5,5,5-hexafluoro-3-pentyn-2-one or an equivalent thereof is contained, into contact with water in the presence of an acid; and it is possible to produce 1,1,1,5,5,5-hexafluoroacetylacetone by dehydration of the thus-formed hydrate.
