A transition-metal-free and base promoted C–C bond forming reaction of benzyl C(sp³)–H bond with organoammonium salts via C–N bond cleavage has been reported. Benzyl ammonium salts as well as cinnamyl ammonium salt could couple readily with various benzyl C(sp³)–H species, producing the corresponding products in moderate to excellent yields with good functional group tolerance. Late stage chemical manipulation enabled the specific 1,2-diarylethane structure of products transformed into useful olefin compounds via dehydrogenation, which further demonstrated the utility of this reaction.

无过渡金属和碱通过有机铵盐的 C-N 键断裂促进 C-C 键的形成

已经报道了无过渡金属和碱促进苄基 C(sp ³ )-H 键与有机铵盐通过C-N 键断裂形成 C-C 键的反应。苄基铵盐和肉桂基铵盐可以很容易地与各种苄基 C(sp ³ )-H 物质偶联，以中等至极好的收率生产相应的产品，并具有良好的官能团耐受性。后期化学操作使产物的特定 1,2-二芳基乙烷结构能够通过脱氢转化为有用的烯烃化合物，这进一步证明了该反应的实用性。
