sequential reaction of nitriles with a Reformatsky reagent and terminal alkynes, is used as an intermediate for divergent palladium‐catalyzed reactions. The reaction pathway of the intermediate is precisely controlled by the choice of the reaction solvent or the palladium catalyst to quickly form four different aromatic scaffolds—arylamines, aminoindenes, pyrroles, and quinolines—starting from readily available
由腈与Reformatsky试剂和末端炔烃的顺序反应形成的溴化锌络合物用作发散的钯催化反应的中间体。中间体的反应路径可通过选择反应溶剂或钯催化剂来精确控制,以从容易获得的腈开始迅速形成四种不同的芳族骨架(芳胺,氨基茚,吡咯和喹啉)。
