Atom-economic threefold cross-couplings of triarylbismuth reagents with 2-halobenzaldehydes and pot-economic in situ Wittig functionalizations with phosphonium salts
An unprecedented synthesis of N‐heteroaromatics from biaryl aldehydes and NH3 through reagent‐free C−H/N−H cross‐coupling has been developed. The electrosynthesis uses NH3 as an inexpensive and atom‐economic nitrogen donor, requires no oxidizing agents, and allows efficient and regioselective access to a wide range of phenanthridines and structurally related polycyclic N‐heteroaromatic products.
通过无试剂的C / H / N-H交叉偶联,由联芳基醛和NH 3合成了N-杂芳族化合物,这是空前的。电合成使用NH 3作为廉价且原子经济的氮供体,不需要氧化剂,并允许有效且区域选择性地访问各种菲啶和结构相关的多环N-杂芳族化合物。
