, p. 2510 - 2515,6 (2012)
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 HClO4 (70 %, aq) was identified as a powerful catalyst for this arylation reaction. Copyright

Friedel-Crafts arylation of α-hydroxy ketones such as 2-hydroxy-1,2,2-triarylethanones has been achieved with a variety of arenes and heteroarenes in the presence of Lewis or Bronsted acids. Both sterically hindered and unhindered 1,2,2,2-tetrarylethanone

Pinacol-pinacolone rearrangement was investigated over Fe-modified montmorillonite K10 catalysts in liquid phase. Exceptional activity was found to be associated with FeCl3 impregnated on K10 through its acetonitrile solution. 100% conversion of benzopinacol was observed in 10 minutes. The catalysts are recyclable.
