A novel and efficient regioselective Friedel–Crafts alkylation reaction of 2-naphthols with electron-rich enamides or enethers initiated by catalytic amounts of stable radical cation triarylaminium salt has been developed. The processes occur under mild conditions.
通过催化量的稳定的自由基阳离子三芳基铵盐引发的2-萘酚与富电子的酰胺或醚的新颖有效的区域选择性Friedel-Crafts烷基化反应已得到开发。该过程在温和的条件下发生。
