In this paper, different mechanochemical methods for production 1, 1´-Bi-2-naphthol from oxidative coupling 2-naphthol
in present of FeCl3 were compared. The first were designed and manufactured a vibration mill as a new mechanochemical
device for this reaction. Our results were compared to the works of Toda et al. and Rasmussen et al who reported other
mechanochemical systems. It was found that our proposed method has a highly yielding with low reaction time. In our
proposed device, there is a possibility to change the vibration frequency from 0 to 4000 rpm and the results of the effect
of different frequencies on reaction progress were presented accordingly. This method was developed for the oxidative
coupling of other phenols such as anthrone and 2,3-dihydroxy-1,4-naphthylene.
