complexes is described that features isolation of a unique silyl ketenimine via aza-Claisen rearrangement, which can be accompanied by an unusual thermal N-to-C 1,3-Ts shift in the formation of tertiary nitriles and a novel cyclopentenimine formation via a palladium-catalyzed aza-Rautenstrauch-type cyclization pathway.
描述了对 ynamido-钯-π-烯丙基配合物的一项引人入胜的机理研究,其特征是通过 aza-Claisen 重排分离出独特的甲硅烷基烯酮亚胺,这可能伴随着不寻常的 N-to-C 1,3-Ts 热转变通过钯催化的氮杂-Rautenstrauch型环化途径形成叔腈和新型环戊烯亚胺。
