Application and preparation of 2,2′-biphenol_Kain Industrial Additive
Background and overview[1] The direct coupling of phenols such as 2,2′-biphenol to the corresponding biphenol derivatives of industrial importance has always been a challenge because these reactions typically have neither regioselectivity nor chemical options sex. The term phenols is used in this application as a class concept and therefore also includes substituted phenols. 2,2”-biphenol can…
