Transalkylation of 4,4′-(1-methylethylidene)bisphenol (2a) with 2,6-diphenylphenol (1b) in the presence of methanesulfonic acid gives 2,2′,6,6′-tetraphenyl-4,4′-(1-methylethylidene) bisphenol (2b) or the intermediate 2,6-diphenyl-4,4′-(1-methylethylidene)bisphenol (6) as product depending on the acid concentration.
