Sulfonated functionalized graphene and grapheneoxide nanosheets were prepared via chemical approaches and their catalytic activities were investigated in the green synthesis of 6,6′-(arylmethylene)bis(2,4-dialkylphenol) antioxidants. In this research, three types of the catalysts including sulfonated reduced grapheneoxide nanosheets (catalyst 1a), sulfonated grapheneoxide nanosheets (catalyst 1b)

was found to be an efficient catalyst for the green synthesis of 6,6′-(aryl(alkyl)methylene)bis(2,4-dialkylphenol) derivatives from 2,4-dialkylphenols and aromatic and aliphatic aldehydes in aqueous media under microwave irradiation. The synthesis of 6,6′-(aryl(alkyl)methylene)bis(2,4-dialkylphenol) derivatives were carried out in the presence of a catalytic amount of RGO-SO3H, under thermal and microwave
