Provided is a method with which an α-allylated cycloalkanone is obtained from a macroyclic compound used as a starting material. The method is a method for producing an α-allylated cycloalkanone represented by General Formula (IV), and the method includes a step of reacting a compound represented by General Formula (I) and/or a compound represented by General Formula (II) with a compound represented by General Formula (III) in the presence of an acid catalyst to produce an α-allylated cycloalkanone represented by General Formula (IV), the acid catalyst including an acid catalyst that includes an ammonium cation and an anion.
