  环烯酮的γ'选择性官能化：通过[4 + 2]环加成/逆曼尼希反应与3取代的马来酰亚胺构筑手性季碳中心

  摘要：

  给出了第一个用3-取代的马来酰亚胺对环烯酮进行有机催化的γ'-选择性官能化的例子，该结果导致了立体选择性的结构季碳中心。这些反应提供了γ'-官能化的环烯酮和β-官能化的环戊烯酮，产率高至优异，具有出色的非对映和对映选择性。DFT计算表明该反应可能以[4 + 2]环加成/复古曼尼希反应进行，这可以解释具有手性季碳中心和出色的立体选择性的意外产物。

  In accordance with the present invention, there are provided novel heterobifunctional monomers and users for the same. Invention compounds have many of the properties required by the microelectronics industry, such as, for example, hydrophobicity, high T g values, low dielectric constant, ionic purity, low coefficient of thermal expansion (CTE), and the like. These properties result in a thermoset that is particularly well suited to high performance applications where typical operating temperatures are often significantly higher than those at which prior art materials were suitable. Invention compounds are particularly ideal for use in the manufacture of electronic components, such as, for example, printed circuit boards, and the like.

• Radical polymerizable compositions containing polycyclic olefins
  申请人：——

  公开号：US20030008992A1

  公开（公告）日：2003-01-09

  In accordance with the present invention, there are provided free-radical polymerizable compositions comprising polycyclic olefins, wherein the polycyclic olefins contain little, if any, cyclopentenyl unsaturation. As a result, these olefins are sufficiently reactive with the propagating free-radicals during cure to provide a highly crosslinked thermoset resin. Moreover, invention compositions comprise high molecular weight polycyclic olefins having low volatility. Accordingly, the observed undesirable weight loss upon cure of prior art thermosetting compositions is considerably reduced. Further provided by the present invention are compositions comprising functionalized polycyclic olefin monomers. These functionalized olefin monomers provide additional benefits such as increased adhesion to a variety of surfaces and greater control over glass transition temperatures.

  根据本发明，提供了由多环烯烃组成的可自由基聚合的组合物，其中多环烯烃几乎不含任何环戊烯不饱和度。因此，这些烯烃在固化过程中与传播的自由基有足够的反应性，从而提供高度交联的热固性树脂。此外，本发明组合物包含挥发性低的高分子量多环烯烃。因此，在固化现有技术的热固性组合物时所观察到的不良重量损失将大大减少。本发明还提供了包含官能化多环烯烃单体的组合物。这些官能化的烯烃单体具有更多的优点，例如增加了对各种表面的附着力，并能更好地控制玻璃化转变温度。
