  在热和微波条件下一锅合成[1,3]-恶嗪和[1,3]-噻嗪衍生物

  摘要：

  据报道，在常规加热以及微波辐射下，可以简单有效地合成取代的苯并[1,3]恶嗪和苯并[1,3]噻嗪衍生物。该化合物是通过使富电子的酚，甲醛和芳族胺在甲醇中反应而获得的。在常规加热下耗时12–16 hr的反应在微波辐射（无溶剂）下在几分钟内成功完成，收率中等至极佳。J.杂环化​​学.2010。

  Disclosed herein are monofunctional benzoxazine compounds having at least one electron-withdrawing group. The monofunctional benzoxazine compounds may be combined with one or more multifunctional benzoxazine compounds to form a unique benzoxazine blend. This benzoxazine blend may be combined with additional components such as catalysts and toughening agents to form a curable resin composition suitable for forming resinous films or composite materials. The presence of monofunctional benzoxazine improves the processability of the benzoxazine-based resin composition by reducing the viscosity of the resin composition, and results in improved tack and drape in the films and composite materials formed from the composition without the loss of modulus in the cured resin.

  本文披露了具有至少一个吸电子基团的单官能苯并噁嗪化合物。这些单官能苯并噁嗪化合物可以与一个或多个多官能苯并噁嗪化合物结合，形成独特的苯并噁嗪混合物。这种苯并噁嗪混合物可以与附加组分（如催化剂和增韧剂）结合，形成适用于形成树脂薄膜或复合材料的可固化树脂组合物。单官能苯并噁嗪的存在通过降低树脂组合物的粘度，改善了基于苯并噁嗪的树脂组合物的加工性能，并在不损失固化树脂的模量的情况下，提高了从该组合物形成的薄膜和复合材料的粘附性和挂褶性。
