at the end of workday.
Personal protective equipment
Eye/face protection
Safety glasses with side-shields conforming to EN166 Use equipment for eye protection tested
and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection
The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and
the standard EN 374 derived from it.
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.
Body Protection
impervious 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.

• Pd(II)-Catalyzed C–H Functionalizations Directed by Distal Weakly Coordinating Functional Groups
  作者：Gang Li、Li Wan、Guofu Zhang、Dasheng Leow、Jillian Spangler、Jin-Quan Yu

  DOI：10.1021/ja5126897

  日期：2015.4.8

  functionalizations of more distal C-H bonds in hydrocinnamoyl ketones, Weinreb amides, and biphenyl Weinreb amides. Mechanistically, the coordination of these carbonyl groups and the bisdentate amino acid ligand with Pd(II) centers provides further evidence for our early hypothesis that the carbonyl groups of the potassium carboxylate are responsible for the directed C-H activation of carboxylic acids.

  开发了广泛使用的合成结构单元苯乙酰基 Weinreb 酰胺、酯和酮的邻-C(sp(2))-H 烯化和乙酰氧基化，无需安装额外的导向基团。远端弱配位和配体加速之间的相互作用对于这些反应在温和条件下进行至关重要。目标CH键和定向官能团之间的较长距离的耐受性还允许在氢化肉桂酰酮、Weinreb酰胺和联苯Weinreb酰胺中对更远端的CH键进行官能化。从机制上讲，这些羰基和双齿氨基酸配体与 Pd(II) 中心的配位为我们早期的假设提供了进一步的证据，即羧酸钾的羰基负责羧酸的定向 CH 活化。
