The sigma complex loses a proton to regain its aromaticity and then the oxyanion becomes protonated.

Alkyl benzene sulfonic acid. A sulfonic acid or sulphonic acid refers to a member of the class of organosulfur compounds with the general formula RSO 2 OH where R is an organic alkyl or aryl group and the SO 2 OH group a sulfonyl hydroxide. As a substituent it is known as a sulfo groupA sulfonic acid can be thought of as sulfuric acid with one hydroxyl group replaced by an organic substituent. Alkyl benzene sulfonic acid labsa.

Benzene will react with sulfur trioxide and in the presence of an acid aryl sulfonic acids are produced. Sulfur trioxide is very reactive electrophile which will sulfonate benzene. The sigma complex loses a proton to regain its aromaticity and then the oxyanion becomes protonated.

Nitro NO 2 sulfonic acid SO 3 H and carbonyl CO substituents have a full or partial positive charge on the atom bonded to the aromatic ring. Structures in which like-charges are close to each other are destabilized by charge repulsion so these substituents inhibit ortho and para substitution more than meta substitution. Consequently meta-products preominate when electrophilic.

Lignin the only biomass component rich in aromatic benzene ring structures is currently underutilized for low-value heat or treated as process waste because of its high chemical resistance. In this review a four-step pathway of pretreatment depolymerization hydrodeoxygenation HDO and alkylation to convert lignin into jet-fuel-range aromatic hydrocarbons and cycloalkanes is explored. When the molar ratio of benzene to alkyl halide falls below 11 para-ditert-butylbenzene becomes the major product.
