Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Harmful by inhalation, in contact with skin and if swallowed.
Irritating to eyes, respiratory system and skin.
Potential Health Effects
Eye:
Causes eye irritation. May cause chemical conjunctivitis.
Skin:
Causes skin irritation. Harmful if absorbed through the skin. May be metabolized to cyanide which in turn acts by inhibiting cytochrome oxidase impairing cellular respiration.
Ingestion:
Harmful if swallowed. May cause irritation of the digestive tract.
Metabolism may release cyanide, which may result in headache, dizziness, weakness, collapse, unconsciousness and possible death.
Inhalation:
Harmful if inhaled. Causes respiratory tract irritation. May be metabolized to cyanide which in turns act by inhibiting cytochrome oxidase impairing cellular respiration.
Chronic:
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.

  Synthesis, ocular effects, and nitric oxide donation of imidazole amidoximes

  摘要：

  Novel 1-R-imidazole-5-amidoximes and I-R-5-cyano-imidazole-4-amidoximes (R: H, Me, Bn) were prepared from their corresponding nitriles and were tested for their efficacy to lower intraocular pressure (IOP) in rabbits. The ability of these compounds to donate nitric oxide (NO) was studied by observing the stimulation of formation of cyclic guanosine-3',5'-monophosphate (cGMP) in the incubation of porcine iris-ciliary body. In the incubation experiments, 1-methylimidazole-5-amidoxime and 1(H)-imidazole-4(5)-amidoxime stimulated formation of cGMP indicating NO donating ability of these compounds. 1-Methylimidazole-5-amidoxime lowered IOP significantly after intravitreal injection.

• Regiochemistry of N-substitution of some 4(5)-substituted imidazoles under solvent-free conditions
  作者：Larisa Oresmaa、Helena Taberman、Matti Haukka、Pirjo Vainiotalo、Paula Aulaskari

  Imidazole-4(5)-carboxaldehyde and 4(5)-cyanoimidazole were N-benzylated and N-methylated using benzyl chloride and methyl iodide on zinc oxide (ZnO), alumina, and KF/alumina under basic conditions without solvent. Triethylamine (Et3N) or potassium carbonate was added as base in the reactions on ZnO and alumina. Imidazole-4(5)-carboxaldehyde was also benzylated on silica and carbon nanotubes. The effect

  在碱性条件下，在无溶剂的情况下，使用苄基氯和甲基碘在氧化锌（ZnO），氧化铝和KF /氧化铝上对N-苄基化和N-甲基化咪唑4（5）-甲醛和4（5）-氰基咪唑。在ZnO和氧化铝上的反应中，加入三乙胺（Et 3 N）或碳酸钾作为碱。咪唑-4（5）-甲醛在二氧化硅和碳纳米管上也被苄基化。研究了碱和固体对1,4-和1,5-取代的化合物的产物分布的影响。在某些情况下，咪唑-4（5）-甲醛和4（5）-氰基咪唑的产物比率不同。在KF /氧化铝上的反应中，两种化合物都偏爱1,4-产物。Et 3的组合N和ZnO有利于1,5-产物，但是腈的作用并不那么明显。当在催化量的氯化锌以Et 3 N为碱的条件下进行醛的N-苄基化和甲基化时，产物分布与在ZnO上的反应相同。在ZnCl 2存在下，腈在ZnO上给出不同的产物比率。另外，当咪唑在KF /氧化铝上被苄基化时，产生了N-苄基咪唑和1，3-二苄基咪唑的混合物。当使用两当量的苄基氯时，仅提供后者的产物。

  日期：1987.10

  The electrooxidation of several 1-methylimidazoles was performed in MeOH that contains NaCN at a platinum anode in a divided cell. Replacement of an aromatic hydrogen by a cyano group occurred. With 1,2,4,5-tetramethylimidazole, the 2,5-addition of cyano groups to the imidazole ring was achieved, and besides side-chain substitution occurred concurrently.

• Competing pathways in the phototransposition of pyrazoles
  作者：John A. Barltrop、A. Colin Day、Arthur G. Mack、Aziz Shahrisa、Shigeru Wakamatsu

  DOI：10.1039/c39810000604

  日期：——

  Cyano-substituted pyrazoles transpose photo-chemically into imidazoles by two concurrent paths: (a) 1,5-interchange, probably by 2,5-bonding to a diazabicyclopentene which isomerises by nitrogen ‘walk’ before rearomatisation, and (b) 2,3-interchange, probably via an intermediate azirine; in sharp contrast, 1,5-dimethyl-3-trifluoromethylpyrazole phototransposes exclusively by the former path.

  氰基取代的吡唑通过两种同时的途径以光化学方式转变为咪唑：（a）1,5-交换，可能通过2,5-结合至二氮杂双环戊烯，该二氮杂双环戊烯在重新芳构化之前通过氮的“游走”而异构化；和（b）2 3-互换，可能是通过中间的叠氮基进行的；与之形成鲜明对比的是，1,5-二甲基-3-三氟甲基吡唑仅通过前者的路径进行光转位。
