The reaction of phenol with aldehydes in the presence of aluminum phenolate leads to mixtures of the corresponding 1,1-bis(hydroxyphenyl)alkanes.The 2,2' or 2,4' isomers predominate, depending on the structure of initial aldehyde.

The reactions between aryloxymagnesium bromides (1) with linear aliphatic aldehydes (2) and their acetals (10) in aprotic solvents of variable donicity have been investigated.In benzene high ortho-regiospecificity is observed in all cases, although with the aldehyde (2) the yield of 2,2'-alkylidenebisphenols (5) is usually low because of the competing aldehyde self-condensation.This process is avoided using diethyl acetals as electrophilic reagents which give the products (5) in good yields.
