5 - Fire Fighting Measures

---

EXTINGUISHING MEDIA
Suitable: For small (incipient) fires, use media such as
ALDRICH www.molbase.com
"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.

8 - Exposure Controls / Personal Protection

---

ENGINEERING CONTROLS
Safety shower and eye bath. Mechanical exhaust required.
GENERAL HYGIENE MEASURES
Wash contaminated clothing before reuse. Wash thoroughly after
handling.
PERSONAL PROTECTIVE EQUIPMENT
Respiratory Protection: Use respirators and components tested and
approved under appropriate government standards such as NIOSH (US)
or CEN (EU). 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.
Hand Protection: Compatible chemical-resistant gloves.

  摘要：

  在芳基ω-卤代烷基酮与碱环合成芳基环烷基酮的过程中，环丙烷的形成速度比环戊烷快23 000倍。氢-氘交换实验和三元环形成的极低的溴化氯化物比率（1.9）与确定酮的去质子速率的反应是一致的。相比之下，在五元环形成中，与羰基相邻的氢-氘交换发生的速度比环化快得多，并且氯-溴化物的比率在“ 99”处为“正常”。在由芳基磺酰基丙基芳烃磺酸酯形成芳基磺酰基环丙烷时，Hammettρ值表示离去基团为+1.7，而对于双磺酰基稳定的碳负离子的分子间取代为+1.2。试图获得ρ LG竞争的分子间反应使五元环形成的值受挫。在先前关于通过分子内亲核取代形成环的工作的背景下讨论了该结果。

  Highly atom-efficient oxidation of sulfides into sulfones under solvent- and catalyst-free reaction conditions using a 30% aqueous solution of H2O2 at 75 °C is reported. A structurally diverse set of phenyl alkyl-, phenyl benzyl-, benzyl alkyl-, dialkyl-, heteroaryl alkyl- and cyclic sulfides were transformed into sulfones regardless of the aggregate state and electronic nature of the substituents
