Pt versus Au: Platinum‐catalysed addition of nucleophiles to allenes follows a distinctly different pathway to the process catalysed by gold(I) complexes; the platinum catalyst leads to different products with indoles involving a bisindolylation reaction, whereas gold(I) gives allyl indoles from a single addition (see scheme).
Pt vs Au:
铂催化的亲核试剂向
丙二烯的加成遵循截然不同的
金(I)络合物催化的过程。
铂催化剂可生成涉及双
吲哚基化反应的
吲哚的不同产物,而
金(I)只需一次添加即可生成烯丙基
吲哚(参见方案)。
