Hexafluorotropone with aqueous sodium hydroxide afforded 2-, 3-, and 4-hydroxypentafluorotropone in the respective proportions, 15:65:20. The tropolone was isolated pure by chelation, and the 3-hydroxide by salt formation, but the 4- isomer was only obtained in admixture with the 3-hydroxide. Each product gave the corresponding methyl tropyl ether on treatment with diazomethane. Treatment of hexafluorotropone
