2,6-Diphenylphenol is a chemical compound from the group of phenols .
Extraction and presentation
2,6-Diphenylphenol can be obtained from cyclohexanone .
properties
2,6-Diphenylphenol is a white solid. It has an orthorhombic crystal structure with the space group P 2 1 2 1 2 1 (space group no. 19) .
use
2,6-Diphenylphenol is used as a ligand in the synthesis of unchelated manganese oxygen clusters and in the preparation of derivatives of pyrazine-2,3-dicarbonitrile , which in turn is required as a precursor for the synthesis of octaazaphthalocyanine derivatives. It can also be polymerized to poly (2,6-diphenyl-p-phenylene oxide) .
It is a starting compound for the production of Reichardt's dye
