Di-alpha-naphthol - Introduction
1,1 '-BINAPHTHYL(1,1'-BINAPHTHYL) is an organic compound containing two naphthalene rings. Its chemical formula is C20H14, and the two naphthalene rings in the structure are connected to the two carbon atoms at the 1 and 1 'positions.
1,1 '-BINAPHTHYL is a white to light yellow crystalline solid with special structure and chemical properties. It is soluble in organic solvents such as chloroform, acetone and benzene.
1,1 '-BINAPHTHYL has a wide range of applications in organic synthesis. As a chiral helical ligand, it can be used to catalyze asymmetric hydrogenation, asymmetric hydrogenation, asymmetric rearrangement and Asymmetric Cyclization. It can also be used as an auxiliary ligand for catalysts for the synthesis of organic compounds with chiral activity.
A common method for preparing 1,1 '-BINAPHTHYL is to react dinaphthalene produced by the dehydrogenation of naphthalene with methyl iodide under alkali catalysis. In the reaction, one naphthalene ring in dinaphthalene is protonated and then alkylated with methyl iodide.
Regarding safety information, 1,1 '-BINAPHTHYL has low toxicity, but as a chemical, it is still necessary to pay attention to safe operation. During handling and storage, the container should be sealed to prevent contact with air. Since 1,1 '-BINAPHTHYL has a tendency to burn, contact with open flames and high temperatures should be avoided. At the same time, it is necessary to avoid contact with strong oxidants and strong acids to prevent dangerous reactions.
