  Anionic [3,3] Rearrangements of Cyclic Hydrazine Diacylates to Medium-Size Cyclic Diamides and Their Structures

  摘要：

  The anionic rearrangement of N,N'-dimethyl-N,N'-diacylhydrazines to 1,2-disubstituted succinamides proceeds in the presence of a ajacent enolate-stabilizing substituent such as a phenyl group. However, a substituent that poorly stabilizes the alpha-carbanion results in an extremely-low yield of the products. The [3,3] sigmatropic rearrangement generally requires a chair form for the cyclic six-centered transition state. When the dienolates of N,N'-diacylhydrazines have favorable steric factors for the cyclic transition state, the rearrangement seems to proceed smoothly. The diacylates of 5- to 8-membered cyclic hydrazine which readily adopt a favorable conformation for the:[33] :rearrangement readily rearrange to 9- to 12-membered cyclic diamides.

Copolymerization of cyclic amides with ε‐caprolactam via an anionic route gave a block copolyamide with a two distinct endotherms in the differential scanning calorimetry analysis. However, copolymerization by the hydrolytic route gave only

  以相当高的收率（〜45％）成功合成了尼龙64的12元环状二酰胺单体。改变合成条件以观察二胺和琥珀酰氯反应物对产率的影响。三倍过量的1,6-六亚甲基二胺（HDA）可获得最高的收率，而进一步增加HDA的量则会降低收率。使用N，N-二异丙基乙胺作为除酸剂导致形成了两种不同的环酰胺，并通过1 H和13进行了全面分析C溶液核磁共振波谱法和质谱法。在差示扫描量热分析中，环状酰胺与ε-己内酰胺通过阴离子途径共聚得到具有两个不同吸热峰的嵌段共聚酰胺。然而，通过水解途径的共聚仅得到具有末端64个单元的尼龙6。©2013 Wiley Periodicals，Inc.
