SECTION 5: Firefighting measures
Extinguishing media
Suitable extinguishing media
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.

Wear self contained breathing apparatus for fire fighting if necessary.
Further information
Use water spray to cool unopened containers.

---

SECTION 6: Accidental release measures

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.

---

Precautions for safe handling
Avoid inhalation of vapour or mist.
Keep away from sources of ignition - No smoking.Take measures to prevent the build up of electrostatic
charge.
For precautions see section 2.2.
Conditions for safe storage, including any incompatibilities
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are
opened must be carefully resealed and kept upright to prevent leakage.

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.
Full contact
Material: Nitrile rubber
Minimum layer thickness: 0,4 mm
Break through time: 480 min
Splash contact
Material: Nature latex/chloroprene
Minimum layer thickness: 0,6 mm
Break through time: 30 min
test method: EN374
If used in solution, or mixed with other substances, and under conditions which differ from EN 374,
contact the supplier of the CE approved gloves. This recommendation is advisory only and must
be evaluated by an industrial hygienist and safety officer familiar with the specific situation of
anticipated use by our customers. It should not be construed as offering an approval for any
specific use scenario.
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
standards such as NIOSH (US) or CEN (EU).
Control of environmental exposure
Prevent further leakage or spillage if safe to do so. Do not let product enter drains.

  仲硼酸酯与 sp2 亲电试剂的立体有择交叉偶联（Suzuki-Miyaura 反应）是合成中长期存在的问题，但在使用钯催化的特定情况下已经取得了进展。然而，目前无法实现与叔硼酸酯的相关偶联。为了解决这一普遍问题，我们专注于利用芳基锂和硼酸酯之间形成的硼酸盐络合物的反应性的替代方法。我们推断，随后添加氧化剂或亲电子试剂会分别从芳环中去除电子或以 Friedel-Crafts 型方式反应，产生阳离子物质，这将引发硼取代基的 1,2-迁移，创建新的 C-C 键。消除（在前一种情况下，在进一步氧化之前）将导致重新芳构化，从而立体特异性地产生偶联产物。最初的工作是用 2-furyllithium 检查的。尽管测试的氧化剂不成功，但亲电试剂，特别是 NBS，使得偶联反应能够以良好的收率与范围广泛的仲和叔硼酸酯发生偶联反应，具有不同的空间需求和官能团（酯、叠氮化物、腈、醇和醚） ）。该反应也适用于其他富电子杂芳烃和
• Substrate-Induced Diastereoselectivity in the Dimethyldioxirane Epoxidation of Simple Alkenes and Dienes
  作者：Amalia Asouti、Lazaros P. Hadjiarapoglou

  DOI：10.1055/s-2001-18751

  日期：——

  Various alkenes and dienes, such as (R)- or (S)-limonene 2, 2-carene 6, 3-carene 8, (R)-α-pinene 10, (S)-α-pinene 12, and endo-dicyclopentadiene 14 were transformed into the corresponding mono- and bis-epoxides by epoxidation with dimethyldioxirane (as an acetone solution). The selectivity observed in these epoxidations is explained by the assumption of hydrogen bonding between bridge protons and the dioxirane.

  各种烯烃和二烯烃，例如（R）-或（S）-柠檬烯2、2-蒈烯6、3-蒈烯8、（R）-α-蒎烯10、（S）-α-蒎烯12以及endo-二环戊二烯14，通过二甲基二氧杂环丙烷（以丙酮溶液形式）的环氧化反应，被转化为相应的单环氧和双环氧化合物。在这些环氧化过程中观察到的选择性可以通过桥连质子与二氧杂环丙烷之间氢键的假设来解释。
