2,2′-Binaphthalene

Description:
2,2′-Binaphthalene, with the CAS number 612-78-2, is an organic compound characterized by its structure, which consists of two naphthalene units connected at the 2-position. This compound is a polycyclic aromatic hydrocarbon (PAH) and is known for its rigidity and planar conformation, which contributes to its unique optical properties. 2,2′-Binaphthalene exhibits chirality, leading to the existence of enantiomers, which are important in various applications, particularly in asymmetric synthesis and catalysis. The compound is typically insoluble in water but soluble in organic solvents such as ethanol and ether. Its melting and boiling points indicate that it is a solid at room temperature. Additionally, 2,2′-Binaphthalene is used in the synthesis of various derivatives and as a building block in organic electronics and materials science due to its electronic properties. Safety considerations should be taken into account, as with many PAHs, due to potential health risks associated with exposure.
