Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.
Storage:
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low.

  摘要：

  替代哌啶和八氢吲哚在可逆有机储氢液方面，作为氢燃料电池的实用性进行了比较。理论高斯计算表明哪些结构特征可能会降低脱氢焓。实验结果显示，将电子供体或共轭取代基连接到哌啶环上大大提高了催化脱氢速率，其中4-氨基哌啶和哌啶-4-甲酰胺的速率最高。观察到了一些不希望的副反应，例如在4-二甲氨基哌啶脱氢过程中发生的烷基转移反应，4-烷氧基和4-氨基吲哚氢化和/或随后脱氢过程中发生的C-O和C-N断裂反应，以及4-氨基吡啶氢化过程中发生的歧化反应。

  使用铑预催化剂氢化 N-杂芳烃：还原消除导致多金属簇的形成

  摘要：

  描述了一种用于氢化 N-杂芳烃的铑催化方法。使用有机金属预催化剂 (η5-C5Me5)Rh(NC)H（NC = 2-苯基吡啶基 (ppy) 或苯并[h]喹啉基（bq））。此外，聚芳族N-杂芳烃的氢化表现出不寻常的化学选择性。对催化剂活化的研究表明，(η5-C5Me5)Rh(bq)H 的光化学或热活化诱导 C(sp2)-H 还原消除并生成双金属配合物 [(η5-C5Me5)Rh(µ2,η2-bq) Rh(η5-C5Me5)H]。在 H2 存在下，(η5-C5Me5)Rh(NC)H 前体和 [(η5-C5Me5)Rh(μ2,η2-bq)Rh(η5-C5Me5)H] 均转化为五金属氢化铑簇，(η5-C5Me5)4Rh5H7，其结构由核磁共振光谱、X射线和中子衍射确定。用每种分离的铑配合物进行吡啶氢化的动力学研究，以鉴定催化相关物质。数据与由未观察到的多金属簇促进的氢化催化最一致，其中形成 (η5-C5Me5)4Rh5H7

  摘要：

  在本文中，我们描述了一系列有效的和选择性的II型代谢型谷氨酸受体（mGluR）激动剂（1S，1'S，2'S）-羧基环丙基甘氨酸（2，L-CCG 1）的一系列α-取代类似物的合成。在氨基酸碳上引入取代基将激动剂2转化为拮抗剂。所有化合物均已制备并测试为一系列四个异构体，即两个外消旋非对映异构体。基于对α-苯乙基类似物3亲和力的改善，在本文中，我们探讨了取代对芳环的影响，作为增加与这些化合物对II型mGluRs的亲和力的策略。II组mGluRs的亲和力是使用[3H]谷氨酸（Glu）在大鼠前脑膜中的结合来测量的。通过测量它们在人类mGluR2和mGluR3转染的RGT细胞中拮抗（1S，3R）-1-氨基环戊烷-1,3-二羧酸诱导的福司柯林刺激的环-AMP抑制作用的能力，证实了它们的拮抗活性。3的芳香环上的间位取代基由各种取代基提供，这些取代基分别是给电子（例如甲基，羟基，氨基，甲氧基，苯基，苯氧基
