Section 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Personal protective equipment
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).
Hand 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.
Eye protection
Tightly fitting safety goggles. Faceshield (8-inch minimum). Use equipment for eye protection tested and
approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin and body protection
Complete suit protecting against chemicals, The type of protective equipment must be selected according
to the concentration and amount of the dangerous substance at the specific workplace.
Hygiene measures
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at
the end of workday.

  摘要：

  已使用简便的后处理工艺以令人满意的收率将仲芳基胺的IBX氧化应用于其官能团向醛的转化。N-苄基甲胺的氧化用作模型底物，并建议IBX氧化剂与胺的比例应为2：1。随后，将几种芳基胺置于这些标准条件下，这表明氧化活性取决于底物中取代基的电子和空间结构。还发现了对仲胺的氧化选择性。

  We report sodium trihydroxyaryl borates as the first robust tetracoordinate organoboron catalysts for reductive functionalization of CO2. These catalysts, easily synthesized from condensing boronic acids with metal hydroxides, activate main group element–hydrogen (E–H) bonds efficiently. In contrast to BX3 type boranes, boronic acids and metal-BAr4 salts, under transition metal-free conditions, sodium

  我们报告三羟基芳基硼酸钠作为第一个坚固的四配位有机硼催化剂，用于CO 2的还原功能化。这些催化剂很容易从硼酸与金属氢氧化物的缩合反应中合成，可以有效地活化主族元素氢键。与BX 3型硼烷，硼酸和金属-BAr 4盐相比，在无过渡金属的条件下，三羟基芳基硼酸钠对各种胺（包括带有官能团的胺）表现出较高的还原性N-甲酰化反应性（106例）例如酯，烯烃，羟基，氰基，硝基，卤素，MeS–，醚基等。催化具有挑战性的吡啶胺的甲酰化反应的性能过高，为使用传统的甲酰化试剂提供了一种有前途的替代方法。机理研究支持将静电相互作用作为Si / B–H活化的关键，从而使碱金属硼酸盐成为用于CO 2加氢硼化，加氢硅烷化和还原甲酰化/甲基化的通用催化剂。
