The Ru-catalyzed meta-C-H benzylation of arenes bearing pyridyl, pyrimidyl, and pyrazolyl directing groups with toluene derivatives has been reported. Heptafluoroisopropyl iodide (CFI) was employed as both a mild oxidant and radical initiator. This reaction showed excellent site-selectivity and tolerated a wide range of functional groups, providing a new strategy for the synthesis of various diarylmethane moieties.
报道了 Ru 催化的带有吡啶基、嘧啶基和吡唑基导向基团的芳基与甲苯衍生物的间 C-H 苄基化反应。全氟异丙基碘(CFI)既可用作温和的氧化剂,也可用作自由基引发剂。该反应表现出优异的位点选择性,并能容忍广泛的官能团,为各种二芳基甲烷部分的合成提供了新策略。
