  日期：2012.9.7

  The gold(I)-catalyzed oxidative rearrangement of propargyl alcohols provides an efficient and selective route to 1,3-diketones under mild conditions. Pyridine-N-oxides were used as external oxidants with, different from related substrates, no alkylidenecycloalkanones or oxetan-3-ones formed as side-products.

  炔丙醇的金（I）催化的氧化重排提供了在温和条件下制备1,3-二酮的有效和选择性途径。吡啶-N-氧化物被用作外部氧化剂，与相关的底物不同，没有形成副产物亚烷基环烷酮或氧杂环丁烷-3-酮。

  Disclosed is a method for producing a metal particle dispersion wherein a metal compound is reduced by using carbodihydrazide represented by the formula (1) below or a polybasic acid polyhydrazide represented by the formula (2) below (wherein R represents an n-valent polybasic acid residue) in a liquid medium. By reducing the metal compound in the presence of a compound having a function preventing discoloration of the metal, there can be obtained a metal particle dispersion having excellent discoloration preventing properties. Metal particles produced by such methods have a uniform particle diameter and are excellent in dispersion stability. By using a conductive resin composition or conductive ink containing a metal particle dispersion obtained by such production methods, there can be formed a conductive coating film, such as a conductive circuit or an electromagnetic layer, having good characteristics.

  本发明公开了一种生产金属颗粒分散液的方法，该方法通过在液体介质中使用下式 (1) 所代表的碳二酰肼或下式 (2) 所代表的多基酸多酰肼（其中 R 代表正价多基酸残基）还原金属化合物。通过在具有防止金属褪色功能的化合物存在下还原金属化合物，可获得具有优异防褪色性能的金属颗粒分散液。通过这种方法制得的金属颗粒具有均匀的颗粒直径和出色的分散稳定性。使用含有通过这种生产方法获得的金属颗粒分散体的导电树脂组合物或导电墨水，可以形成具有良好特性的导电涂膜，例如导电电路或电磁层。
