For small (incipient) fires, use media such as "alcohol" foam, dry chemical, or carbon dioxide. For large
fires, apply water from as far as possible. Use very large quantities (flooding) of water applied as a mist or
spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of
water.

Avoid breathing vapours, mist or gas. Remove all sources of ignition. Beware of vapours accumulating to
form explosive concentrations. Vapours can accumulate in low areas.
For personal protection see section 8.
Environmental precautions
Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
Methods and materials for containment and cleaning up
Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and
place in container for disposal according to local regulations (see section 13).
Reference to other sections
For disposal see section 13.

SECTION 8: Exposure controls/personal protection
Control parameters
Components with workplace control parameters
Exposure controls
Appropriate engineering controls
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and
at the end of workday.
Personal protective equipment
Eye/face protection
Face shield and safety glasses Use equipment for eye protection tested and approved under
appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique
(without touching glove's outer surface) to avoid skin contact with this product. Dispose of
contaminated gloves after use in accordance with applicable laws and good laboratory practices.
Wash and dry hands.
The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and
the standard EN 374 derived from it.
Body Protection
impervious clothing, Flame retardant antistatic protective clothing, The type of protective
equipment must be selected according to the concentration and amount of the dangerous
substance at the specific workplace.
Respiratory protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator
with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup
to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air
respirator. Use respirators and components tested and approved under appropriate government

  发现4-取代的吡咯烷酮丁酰胺作为具有显着抗癫痫活性的新药物。

  摘要：

  （S）-α-乙基-2-氧代吡咯烷乙酰胺2（左乙拉西坦，Keppra，UCB SA）是吡乙酰胺的结构类似物，最近已被批准作为成人难治性部分发作的附加治疗药物。由于独特的作用机理，该药物似乎具有显着的功效和高耐受性。后者涉及2的脑特异性结合位点（左乙拉西坦结合位点为LBS），可能在其抗癫痫特性中起主要作用。使用这种新型分子靶标，我们启动了一项药物发现计划，以寻找对LBS具有显着亲和力的配体，以表征其在癫痫和其他中枢神经系统疾病中的治疗潜力。我们系统地研究了吡咯烷酮乙酰胺支架的各个位置。我们发现（i）2上的羧酰胺部分对于亲和力是必不可少的；（ii）在100个不同的侧链中，优选的羧酰胺取代α是具有（S）-构型的乙基；（iii）2-氧吡咯烷环优于哌啶类似物或无环化合物；（iv）内酰胺环的3或5位取代降低了LBS亲和力；（v）内酰胺环被小的疏水基团4-取代改善了体外和体内的效力。已显示在4位上取代的6种有趣的候选物在体内比2种更有效。

  The hydrogenation of esters catalyzed by a manganese complex of phosphine-aminopyridine ligand was developed. Using this protocol, a variety of (hetero)aromatic and aliphatic carboxylates including biomass-derived esters and lactones were hydrogenated to primary alcohols with 63–98% yields. The manganese catalyst was found to be active for the hydrogenation of methyl benzoate, providing benzyl alcohol

  日期：2016.12

  70 years, numerous catalyst systems have been developed that allow for highly linear-selective (anti-Markovnikov) reactions and are used in industry to produce linear carboxylates starting from olefins. In contrast, a general catalyst system for Markovnikov-selective alkoxycarbonylation of aliphatic olefins remains unknown. In this paper, we show that a specific palladium catalyst system consisting

  加氢酯化反应代表了羰基化反应的基本类型，并且构成了均相催化的最重要的工业应用之一。在过去的70年中，已经开发了许多催化剂系统，这些系统可以进行高度线性选择（反马氏力）反应，并在工业上用于从烯烃开始生产线性羧酸盐。相比之下，用于脂族烯烃的马尔科夫尼科夫选择性烷氧基羰基化的一般催化剂体系仍然是未知的。在本文中，我们显示了由PdX 2 / N组成的特定钯催化剂体系-苯基吡咯膦（X，卤化物）催化各种烯烃的烷氧基羰基化，以高选择性（支链选择性高达91％）得到支链酯。观察到的（和意想不到的）选择性已经通过包括色散校正在内的密度泛函理论计算得到了合理化。
