  Synthesis of Anthracene and Azaanthracene Fluorophores via [2+2+2] Cyclotrimerization Reactions

  摘要：

  A highly convergent [2+2+2]-cyclotrimerization approach to anthracenes and 2-azaanthracenes has been developed. It allows for the facile introduction of the anthracene moiety on alkyne and nitrile bearing molecules and the rapid construction of compound arrays. This is showcased in the assembly of a collection of fluorophores and their photochemical evaluation.

  烧结碳化硅：一种用于单模反应器中微波化学的新型陶瓷容器材料

  摘要：

  碳化硅（SiC）是一种强烈吸收微波的化学惰性陶瓷材料，由于其高熔点和非常低的热膨胀系数，因此可以在极高的温度下使用。微波辐射会在半导体陶瓷中感应出电子流，从而通过电阻加热机制非常有效地加热材料。碳化硅反应容器与单模微波反应器的结合使用，几乎可以完全屏蔽电磁场中的内容物。因此，这样的实验不会对化学过程产生电磁场影响，因为半导体陶瓷小瓶可以有效地防止微波辐射穿透反应混合物。通过比较微波透明派热克斯玻璃瓶中的结果与在相同反应温度下在SiC玻璃瓶中进行的实验，评估了电磁场效应（特定/非微波微波效应）对21种选定化学转化的影响。对于21种反应中的大多数，使用两种不同的样品瓶类型在转化率/纯度/产物收率方面的结果实际上是相同的，这表明电磁场对反应路径没有直接影响。由于SiC的高耐化学性，可以在不降解容器材料的情况下进行涉及腐蚀性试剂的反应。例如，使用三乙胺三氟化氢的高温氟-氯交换反应，以及用氢氧化钾水溶液水解腈。

• An Investigation of Wall Effects in Microwave-Assisted Ring-Closing Metathesis and Cyclotrimerization Reactions

  Challenging Ru-catalyzed ring-closing metathesis transformations leading to eight-membered-ring systems and Ni- or Co-catalyzed [2+2+2] cyclotrimerizations were evaluated at elevated temperatures applying microwave dielectric heating or conventional thermal heating in order to investigate the role of wall effects. All reactions were conducted in a dedicated reactor setup that allowed accurate internal reaction temperature measurements using fiber-optic probes for both types of heating modes. For ring-closing metathesis best results were achieved using an open vessel gas sparging protocol in 1,2-dichloroethane at reflux temperature (83 degrees C), while cyclotrimerizations were performed under sealed vessel conditions in toluene between 80 and 160 degrees C. For all studied transformations the results achieved in a single-mode microwave reactor could be reproduced by conventional heating in an oil bath by carefully matching the temperature profiles as close as possible during the entire heating and cooling cycle. In contrast to previous literature reports, no evidence that direct in-core microwave heating can increase catalyst lifetime by minimization or elimination of wall effects was obtained. At the same time, no indication for the involvement of nonthermal microwave effects in these homogeneous transition metal-catalyzed transformations was seen.

  Silicon carbide (SiC) is a strongly microwave absorbing chemically inert ceramic material that can be utilized at extremely high temperatures due to its high melting point and very low thermal expansion coefficient. Microwave irradiation induces a flow of electrons in the semiconducting ceramic that heats the material very efficiently through resistance heating mechanisms. The use of SiC carbide reaction
