An efficient partnership: A new synthesis of heteroatom‐containing o‐teraryls from aryl iodides and heteroarenes is based on the palladium/norbornene dual catalytic system and involves sp2 CH activation both in the arylation step leading to biaryl and in the subsequent one involving arylation of the heterocycle (see scheme). The synthesis combines the ubiquitous biaryl structure with heterocyclic
一种有效的合作伙伴关系:基于钯/降冰片烯双催化体系,从芳基碘化物和杂芳烃合成含杂原子的邻四芳基化合物,在芳基化步骤和随后的芳基化步骤中都涉及 sp 2 C H 活化涉及杂环的芳基化(见方案)。该合成将普遍存在的联芳基结构与杂环在温和条件下的一锅反应中结合起来。
