title: A highly efficient Friedel-Crafts reaction of tertiary α-hydroxyesters or α-hydroxyketones to α-quaternary esters or ketones.
abstract: A catalytic Friedel-Crafts arylation of α-hydroxyesters or α-hydroxyketones with electron-rich aromatic compounds to furnish α-quaternary esters/ketones has been developed. The cheap and easy to handle catalyst HClO(4)  (70 %, aq) was identified as a powerful catalyst for this arylation reaction.
