A new convenient Friedel-Crafts alkylation of aromatic compounds with secondary alcohol methanesulfonates in the presence of scandium(III) trifluoromethanesulfonate or trifluoromethanesulfonic acid as the catalyst

Scandium(III) triflate and triflic acid were both found to be efficient catalysts for the Friedel-Crafts alkylation of aromatic compounds using methanesulfonates derived from secondary alcohols as alkylating agents.

Process for preparing 2,5-diphenylterephthalic acid by oxidation

Provided is a process for preparing 2,5-diphenylterephthalic acid, which is useful in preparing certain polyesters, especially liquid-crystalline polyesters. In this process, p-xylene is di-alkylated with cyclohexene to provide 2,5-dicyclo-hexyl-p-xylene, which is in turn dehydrogenated to provide 2,5-diphenylxylene. 2,5-Diphenylxylene is then oxidized to provide 2,5-diphenylterephthalic acid by utilization of a cobaltous/manganous/bromide oxidation system.
