  II型和III型氰脂的合成

  摘要：

  通过一种非常简单的方法即可合成出具有杀虫活性的II型和III型氰脂。在非极性溶剂中使用相转移催化剂将脂肪酸盐与1,3-二溴丙酮或溴丙酮酯化，然后进行Wittig缩合反应，可高产率提供多种氰脂。

• Silver Nanoparticles Capped by Long-Chain Unsaturated Carboxylates
  作者：Wei Wang、Xiao Chen、Shlomo Efrima

  DOI：10.1021/jp991101q

  日期：1999.8.1

  We study the preparation and capping of silver nanoparticles by several unsaturated long-chain carboxylates. UV-visible and FTIR spectroscopy and high-resolution electron microscopy are used to characterize the effect of the chain length, its configuration, and the degree of unsaturation on the size distribution of the nanoparticles. Langmuir layers and Langmuir-Blodgett films are used to study the adsorption of these carboxylates on the particles. We find that unsaturated carboxylates in the cis configuration are useful stabilizers for the control of particle size and its surface properties.
