Abstract
An industrially excellent production method for cycloalkyl(trifluoromethyl)benzene is free of complicated steps, small in the number of steps, and high in production efficiency. Cycloalkyl(trifluoromethyl)benzene is produced by reacting a halogen-substituted trifluoromethyl benzene with magnesium metal to produce a Grignard reagent and cross-coupling the Grignard reagent with a cycloalkyl halide in the presence of an iron salt or a cobalt salt at a reaction temperature of 60° C. to 80° C.
