  Highly Selective Intra- and Intermolecular Coupling Reactions of Diazo Compounds to Form cis-Alkenes Using a Ruthenium Porphyrin Catalyst

  摘要：

  [Ru(2,6-Cl2TPP)(CO)] catalyzed intramolecular coupling reactions of bisdiazoacetates and intermolecular coupling reactions of monodiazoacetates to afford the coupling products in up to 76% and 93% yields, respectively. Only the cis isomers were obtained from the reactions. Employing such a ruthenium-catalyzed coupling reaction of a diazo compound as a key step allowed the synthesis of Patulolide B in 67% yield with a ratio of >40:1 against its trans isomer.

  采用缩聚反应的高弹性和可降解玻璃弹性体

  摘要：

  在聚合物基体中引入共价交联网络可以融合聚合物在再加工和耐久性方面的优势。在这项贡献中，通过缩聚获得了一系列高性能玻璃弹性体。通过改变双乙酰乙酸酯、六取代双乙酰乙酸酯、双胺和三(2-氨基乙基)胺的进料比来调节聚合物的拓扑结构。通过这些结构操作，得益于长链支化的引入，玻璃体弹性体呈现出良好的弹性恢复性能（应变恢复值高达 80%）。此外，弹性体表现出优异的再加工性能、水蒸气/氧气阻隔性和粘合性能。特别是，弹性体在酸性条件下可以降解为单体，使得弹性体能够在闭环回收系统中再次合成。这项工作中缩聚的简便性可制备高弹性和可回收的玻璃弹性体，这为合成可持续聚合物提供了令人兴奋的机会。

  Provided is a Michael addition product prepared from a multifunctional acryl monomer having multiple hydroxyl groups allowing introduction of acryl functional groups, as a Michael acceptor, and a Michael donor. The Michael addition product is a novel multifunctional compound having an oligomer and a photoinitiator moiety in the molecule. Since it can be cured under a standard UV curing condition without having to add a photoinitiator, it is reduced to air pollution or health problem. Therefore the superior physical properties were obtained by cured coatings without surface tackiness. In addition, its hydroxyl groups allow, through isocyanate bonding or introduction of acryl groups, 3-dimensional crosslinking and molecular and compositional design for improving expandability, friction, and reactivity and hydrophilicity for self-adhesion, hardness of cured film, or the like. Consequently, a very useful, multifunctional or water-dispersible coating composition may be prepared.

  提供的是从具有多个羟基的多功能丙烯酸单体制备的Michael加成产物，允许引入丙烯酸功能团作为Michael受体和Michael给体。该Michael加成产物是一种新颖的多功能化合物，在分子中具有寡聚体和光引发剂基团。由于它可以在标准紫外光固化条件下固化，无需添加光引发剂，因此减少了空气污染或健康问题。因此，通过固化涂层获得了优越的物理性能，而无需表面粘性。此外，其羟基通过异氰酸酯键合或引入丙烯基，允许进行三维交联和分子和组成设计，以改善可扩展性、摩擦、反应性和亲水性，用于自粘附、固化膜的硬度等。因此，可以制备非常有用的多功能或水分散性涂料组合物。

  多组分组合聚合方法已被用作组合化学、聚合物化学和有机化学之间的新交叉点。三组分 Biginelli 反应已被用作模型多组分反应 (MCR)，以有效地制备具有不断变化的链结构但物理性质不同的缩聚物库。自然增加的反应模块（单体）直接使库中聚合物的数量增加了一倍，有效提高了聚合物制备的效率。首次绘制了这些同源聚合物的玻璃化转变温度 (Tg) 以预测不存在的聚合物同系物的 Tg 值，并且具有良好到出色的准确度。同时，Tg图还被用来揭示Tg根据聚合物结构（连接基团、单体链长等）的规律变化，初步表明了多组分组合聚合体系的学术意义。我们相信，当前的研究为通过 MCR 合成新的聚合物库铺平了道路，并可能促进跨学科领域对 MCR 的更广泛研究。
