A Facile Preparation of 2,2'-Diphenyl-4,4'-dihydroxybiphenyl - A New Synthetic Route
E-mail:
Nickel(0)-catalyzed homocoupling of aryl mesylate of 4-protected-2-substituted hydroquinone was utilized in the key step of a reaction scheme which leads to the synthesis of 2,2'-diphenyl-4,4'-dihydroxybiphenyl. The new synthetic procedure reported in this paper started from the commercially available 2-phenylphenol as a starting material.
