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.
已经开发了α-羟基酯或α-羟基酮与富电子芳族化合物的催化弗里德-克拉夫特芳基化反应,以提供α-季酯/酮。廉价且易于处理的催化剂HClO 4(70%,aq)被确定为该芳基化反应的有力催化剂。
