traditional cross‐coupling methods. An alternative approach is presented where pyridines and diazines are converted into heteroaryl phosphonium salts and coupled with aryl boronic acids. Nickel catalysts are unique for selective heteroaryl transfer, and the reaction has a broad substrate scope that includes complex pharmaceuticals. Phosphonium ions also display orthogonal reactivity in cross‐couplings compared

cross-couplings of nitroarenes and heteroarylboronate esters has been developed. A number of heterobiaryl compounds containing pyridine, pyrimidine, quinoline, furan, thiophene, and pyrazole were prepared using [Pd(cinnamyl)Cl]2/2-aryl-5-(2,4,6-triisopropylphenyl)-2,3-imidazolylidene[1,5-a]pyridines as the catalysts in good to excellent yields. The synthetic practicality of this approach is demonstrated through
已经开发了钯催化的硝基芳烃和杂芳基硼酸酯的 Suzuki-Miyaura 交叉偶联。使用[Pd(肉桂基)Cl] 2 /2-芳基-5-(2,4,6-三异丙基苯基)-2,3-制备了许多含有吡啶、嘧啶、喹啉、呋喃、噻吩和吡唑的杂二芳基化合物咪唑亚基[1,5- a ]吡啶作为催化剂,收率良好。这种方法的合成实用性通过类药物分子的合成得到证明。
