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.
在本公开的一种生产方法中,1,1'-联萘前体衍生物、有机酸和碘化剂或溴化剂混合在一起。1,1'-联萘前体衍生物具有 1,1'-联萘骨架,并在 1,1'-联萘骨架的 2-位和 1,1'-联萘骨架的 2'-位上具有一个电子供能基团,电子供能基团包含一个直接键合到骨架上的氧原子。利用本公开的生产方法,可以获得在 1,1'- 联萘骨架的 8 位和/或 8'- 位上引入取代基的 1,1'- 联萘衍生物。通过本公开的生产方法获得的 1,1'-联萘衍生物可以是一种化合物,进一步具有在选自 1,1'-联萘骨架的 4-位、4'-位、5-位、5'-位、6-位和 6'-位的至少一个位置上引入的取代基。
