摘要
In a production method of the present disclosure, a 1,1′-binaphthyl precursor derivative, an organic acid, and an iodinating or brominating agent are mixed. The 1,1′-binaphthyl precursor derivative has a 1,1′-binaphthyl skeleton and has an electron-donating group at the 2-position of the 1,1′-binaphthyl skeleton and at the 2′-position of the 1,1′-binaphthyl skeleton, and the electron-donating group contains an oxygen atom directly bonded to the skeleton. With the production method of the present disclosure, a 1,1′-binaphthyl derivative having a substituent introduced at the 8-position and/or 8′-position of the 1,1′-binaphthyl skeleton can be obtained. The 1,1′-binaphthyl derivative obtained by the production method of the present disclosure can be a compound further having a substituent introduced at at least one position selected from the 4-position, 4′-position, 5-position, 5′-position, 6-position, and 6′-position of the 1,1′-binaphthyl skeleton.
