The reaction of 2,2'-spirobichroman derivatives with either hydrobromic acid in the acetic acid solution or aluminum chloride in the chlorobenzene solution yielded 1,1'-spirobiindan-4,4'-diol analogues.The reaction is peculiar as compared with the reaction of alkyl aryl ethers with the same reagents in the same media.
