Allyl amides were synthesised from the reaction of allylalcohols and halogenated nitriles using a platinum multifaceted catalysis approach in which both the nucleophilic addition and subsequent [3,3]-sigmatropic rearrangement steps of the process were catalysed by the same complex. Additionally, 1H/13C1H} NMR and GC studies provided the first insights into the mechanism of this transformation.
使用铂多面催化方法从烯丙醇与卤化腈的反应中合成烯丙基酰胺,其中该过程的亲核加成和随后的[3,3]-σ重排步骤均由相同的配合物催化。此外,1 H / 13 C 1 H} NMR和GC研究提供了对该转化机理的初步见解。

Palladium-catalyzed hydroalkylation of allylic amine derivatives by alkylzinc reagents is reported. This reductive cross-coupling reaction yields anti-Markovnikov products using a variety of allylic amine protecting groups. Preliminary mechanistic studies suggest that a reversible β-hydride elimination/hydride insertion process furnishes the primary Pd-alkyl intermediate, which then undergoes transmetalation
