to internal alkenes affords the construction of vicinal diamines. In the presence of a palladium catalyst, the reaction proceeds through two mechanistically different C-N bond formation reactions. It is initiated by aminopalladation, followed by a reductive amination of a palladated secondary carbon. The overall process proceeds with complete selectivity for both steps and thereby generates a convenient
两个磺酰胺顺序转移到内部烯烃提供了连二胺的结构。在钯催化剂的存在下,反应通过两个机械不同的 CN 键形成反应进行。它由氨基钯化引发,然后是钯化仲碳的还原胺化。整个过程对两个步骤都具有完全的选择性,从而可以方便地获得杂环结构,例如双吲哚、退火二氢吲哚和双吡咯烷。
