tert-Butylation of Aromatic Hydrocarbons with AlCl3-tert-Butylanisole Catalyst
tert-Butylation of aromatic hydrocarbons with tert-butyl chloride in the presence of AlCl3-tert-butylanisole was investigated. Neither isomerization of the products nor transalkylation of the substrate with the products was observed when the molar ratio of tert-butylanisole to AlCl3 was more than two. Competitive tert-butylation of benzene and toluene showed higher substrate selectivity (kT/kB=21-24). A role of trans-tert-butylation in the tert-butylation was suggested from the results of tert-butylation of toluene in the presence of 2, 4- and 2, 5-dimethylanisole.
