我们开发了一种高效的合成平台,用于制备基于双官能 sydnone 与三官能炔烃的 1,3-偶极环加成反应的新型高性能热固性塑料。这些可加工材料具有出色的热稳定性,520 °C 下的 Td5% 和 225 °C 下每天的重量损失 <0.1%(均在空气中)。这种性能的关键是起始官能团的稳定性,它允许通过简单的热活化进行反应性 B 阶跃,以提供完全芳香族和高度交联的基于聚吡唑的热固性材料。

on the 1,3-dipolar cycloaddition of a bifunctional sydnone with a trifunctional alkyne. These processable materials possess outstanding thermal stability, with Td5% of 520 °C and a weight loss of <0.1% per day at 225 °C (both in air). Key to this performance is the stability of the starting functional groups that allows for reactive B-staging via simple thermal activation to give fully aromatic and

complexes bearing n-OBu substituents in the peripheral or non-peripheral positions are efficient catalysts for the selective double or single carbene insertion to the amine N–H bonds. This complementary reactivity of two Ru complexes can be used for the synthesis of asymmetric tertiary amines and diamines bearing different substituents and has been demonstrated by two examples of readily available primary
