carbon–heteroatom (C–P, C–O, C–S, and C–N) bonds via C–N cleavage of benzyl ammonium salts under transition-metal-free conditions was reported. The combination of t-BuOK and 18-crown-6 enabled a wide range of substituted benzyl ammonium salts to couple readily with different kinds of heteroatom nucleophiles, i.e. hydrogen phosphoryl compounds, alcohols, thiols, and amines. Good functional group tolerance was demonstrated
据报道,在无过渡金属的条件下,通过苄基铵盐的C–N裂解,可以轻松而通用地构建碳-杂原子(C–P,C–O,C–S和C–N)键。的组合吨-BuOK和18-冠-6启用广泛取代的苄基铵盐的耦合容易地与不同类型的杂原子的亲核试剂,即,氢磷化合物,醇,硫醇和胺。证明了良好的功能组耐受性。还成功进行了放大反应和一锅合成。
