Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Harmful in contact with skin and if swallowed.The toxicological properties of this material have not been fully investigated.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be metabolized to cyanide which in turn acts by inhibiting cytochrome oxidase impairing cellular respiration.
Ingestion:
May cause irritation of the digestive tract. May cause cardiac disturbances. The toxicological properties of this substance have not been fully investigated. May cause central nervous system depression.
Metabolism may release cyanide, which may result in headache, dizziness, weakness, collapse, unconsciousness and possible death.
Inhalation:
May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. May cause cardiac abnormalities. May be metabolized to cyanide which in turns act by inhibiting cytochrome oxidase impairing cellular respiration.
Inhalation at high concentrations may cause CNS depression and asphixiation.
Chronic:
May be metabolized to cyanide which in turn acts by inhibiting cytochrome oxidase impairing cellular respiration. Chronic exposure to cyanide solutions may lead to the development of a "cyanide" rash, characterized by itching, and by macular, papular, and vesicular eruptions, and may be accompanied by secondary infections. Exposure to small amounts of cyanide compounds over long periods of time is reported to cause loss of appetite, headache, weakness, nausea, dizziness, and symptoms of irritation of the upper respiratory tract and eyes.

Section 4 - FIRST AID MEASURES
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician:
May be partially metabolized to cyanide in the body.
Antidote: Always have a cyanide antidote kit on hand when working with cyanide compounds. Get medical advice to use.

  Exploring the reactivity of nickel complexes in hydrodecyanation reactions

  摘要：

  In the present study, the nickel-catalyzed hydrodecyanation of organic cyanides with lithium borohydride as a cheap hydride source has been examined in detail. As precatalysts straightforward nickel complexes modified by tridentate O,N,O'-ligands and triphenylphosphane as co-ligand have been applied. Noteworthy, excellent yields and chemoselectivities were feasible for a variety of organic cyanides at low catalyst loadings and low temperature (70 degrees C) within short reaction time (3 h).

  摘要：

  我们已经开发出一种清洁，原子经济且环保的方法，通过将新的双N-杂环碳烯-氮-膦配体R（CNP）2（R = 邻-二甲苯基）与钌前体结合，将胺无接受地脱氢为腈。将[RuCl 2（η 6 -C 6 H ^ 6）] 2。在该系统中，胺的电子和空间因素对反应的影响可忽略不计，并且广泛耐受各种官能团。所有研究的胺都可以优良的选择性转化为腈，收率高达99％。该系统空前的催化性能归因于两个被R（CNP）2螯合的钌中心的协同作用，并且根据通过原位NMR和HRMS发现的活性物种，提出了合理的反应机理。

• From aldehydes to nitriles, a general and high yielding transformation using HOF·CH3CN complex
  作者：Mira Carmeli、Neta Shefer、Shlomo Rozen

  DOI：10.1016/j.tetlet.2006.10.014

  日期：2006.12

  N,N-Dimethylhydrazones of aldehydes undergo a rapid oxidative cleavage to form nitriles in very high yields on reaction with HOF·CH3CN under mild conditions. The reaction is chemoselective and proceeds rapidly without racemization. The nitriles were resistant to further oxidation, even when a large excess of the reagent was employed.

Furthermore, the cyanide- and thiol-free reaction shows high functional group tolerance and great efficiency for the late-stage derivatization of commercial molecules. Finally, synthetic applications

  A cobalt complex catalyzed tandem conversion of nitrile to N-methylated amide is described using a methanol and water mixture. Using this protocol, several nitriles were directly and efficiently converted to the desired N-methylated amides.
