Two transition-metal-free methods to access substituted phenols via the arylation of silanols or hydrogen peroxide with diaryliodonium salts are presented. The complementary reactivity of the two nucleophiles allows synthesis of a broad range of phenols without competing aryne formation, as illustrated by the synthesis of the anesthetic Propofol. Furthermore, silyl-protected phenols can easily be obtained
提出了两种无过渡金属的方法,可通过硅烷醇或过氧化氢与二芳基碘鎓盐的芳基化来获得取代的苯酚。两种亲核试剂的互补反应性可合成多种酚,而不会形成竞争性的芳烃形成,如麻醉药异丙酚的合成所示。此外,可以容易地获得甲硅烷基保护的苯酚,其适合于进一步的转化。
