Abstract The reaction of 1, 2‐dibromo‐1, 2‐bis(4‐methoxyphenyl)ethane with alcohols was associated with rearrangement to give the corresponding bis(4‐methoxyphenyl)acetals. In boiling ethylene glycol 4,4′‐dimethoxy‐deoxybenzoin was also obtained due to an aldehyde‐ketone rearrangement. 4,4′‐Dimethoxybenzophenone was also formed being apparently derived from the acetals. The mechanism of formation of the acetals has been discussed.
