  N-杂环卡宾催化的双取代Michael受体的尾到尾二聚和Rauhut-Currier反应

  摘要：

  已经研究了N-杂环卡宾（NHC）催化的各种双取代Michael受体的二聚反应。除了先前报道的甲基丙烯酸酯的尾到尾二聚以外，亚乙烯基底物的范围还扩大到了γ-甲基-α-亚甲基-γ-丁内酯，2-亚甲基戊二酸二甲酯，衣康酸二甲酯，甲基丙烯酰胺和2-异丙烯基苯并恶唑。其中的一些已被金属催化的对应物二聚化。相反，可能由于β-取代基的空间位阻，诸如丁烯腈，巴豆酸甲酯和2-环己烯-1-酮的亚乙烯基底物不经历二聚化。相反，发现这些的Rauhut-Currier（RC）反应正在进行。

  A water-swellable composition for water-leakage prevention useful in construction works is a compounded material comprising (A) 100 parts by weight of an elastomer such as polychloroprene rubber and (B) 20 to 300 parts by weight of a highly water-absorptive resin which is a crosslinked material of a copolymer of a ternary monomeric mixture composed of (meth)acrylic acid, an ester of (meth)acrylic acid having a sulfonic acid group, for example a compound of the formula CH₂=CR-CO-OCH₂SO₃X, R being H or methyl, X being H or a monovalent cation and n being an integer of at least 2, such as sodium 2-sulfoethyl acrylate, and (meth)acrylamide in a specified proportion. The crosslinks are formed either by reacting the copolymer with a crosslinking agent such as propylene glycol or by copolymerizing the monomers in the presence of a copolymer­izable crosslinking agent such as N,N-methylene bisacryl­amide. The composition is capable of exhibiting stable swelling pressure and strength even in water containing polyvalent metal ions, e.g., calcium ions.

  Disclosed is a method for producing a silver-containing nanostructure which can reduce the time required for a post treatment step and the amount of a waste material and which is achieved by the application of the reduction reaction of silver oxide; and a silver-containing nanostructure having a specific structure, which can be produced by the method. Specifically disclosed is a method for producing a silver-containing nanostructure, including dispersing a polymeric compound in which a hydrophilic segment is bonded to a polyalkyleneimine chain in a medium, adding silver oxide thereto, and carrying out a reduction reaction of the silver oxide, thereby obtaining a silver-containing nanostructure. In the method, a structure having a branched structure can be produced when a specific compound is used as a complexing agent. The silver-containing nanostructure thus produced can be used as a conductive paste or the like.
