Abstract
A simple production process is provided of a perfluoroalkyl compound that uses monohydroperfluoroalkane as a starting material, the perfluoroalkyl compound being an important intermediate of organic electronic materials, medicine, agricultural chemicals, functional polymer materials and the like. With monohydroperfluoroalkane is reacted a base and then a carbonyl compound to produce an alcohol having a perfluoroalkyl group. For example, potassium hydroxide is made to interact with trifluoromethane, and a reaction with a carbonyl compound is induced to produce an alcohol having a trifluoromethyl group.
