Add time:08/26/2019 Source:sciencedirect.com
A practical protocol to obtain 1,1′-binaphthyl-2,2′-diamine was developed from 2-naphthol and 2-naphthylhydrazine under mild conditions: solvent-free, 125–130 °C, atmospheric pressure. The convenient procedure makes the process amenable for large-scale synthesis of the versatile compound.
