A single set of reaction conditions for the palladium‐catalyzed amination of a wide variety of (hetero)aryl halides using primary alkyl amines has been developed. By combining the exceptionally high reactivity of the Pd‐PEPPSI‐IPentCl catalyst (PEPPSI=pyridine enhanced precatalyst preparation, stabilization, and initiation) with the soluble and nonaggressive sodium salt of BHT (BHT=2,6‐di‐tert‐butyl‐hydroxytoluene)
已经开发了使用伯烷基胺对钯催化的多种(杂)芳基卤化物进行胺化反应的一套反应条件。通过将Pd-PEPPSI-IPent Cl催化剂的超高反应性(PEPPSI =吡啶增强的预催化剂的制备,稳定化和引发)与BHT的可溶性非侵蚀性钠盐(BHT = 2,6-二叔丁基-六元和五元(杂)芳基卤化物都经过高效且选择性的胺化作用。
