摘要：

A green and efficient nucleophilic addition reaction of trifluoromethyl ketone with pyrazolone was developed under "on water" conditions, affording pyrazolone substituted tertiary trifluoromethyl alcohols in high yields. The advantages of being catalyst-free, column chromatography-free, environmentally benign and easy workup make it a promising method for preparation of a variety of pyrazolone substituted tertiary trifluoromethyl alcohols.
