2,2′-Biphenol is an
Synthesis
The chemical can be made by a hydrolysis reaction that opens the central ring of dibenzofuran. Alternatively, it can be produced from 2,4-di-tert-butylphenol in two steps. The first step entails oxidative coupling to give the 2,2′-biphenol with four tert-butyl substituents. This species then undergoes debutylation.[3]
