Linear alkylbenzenes (LAB), the primary intermediates in detergent industry, are commercially manufactured by the alkylation of benzene with C10–14 n-alkenes.[1–3] Among LAB isomers, 2-phenyl isomers are the most favorable starting materials for the production of ecofriendly domestic and industrial detergents because of their high solubility and biodegradability. The development of catalysts with a high selectivity to 2-phenyl isomers in benzene alkylations is an area of great interest. The alkylation of benzene with olefins proceeds through a carbonium ion mechanism. The relative stabilities of the formed carbonium ions increase with the carbon number towards the center of olefin chains. .....
