• THE REACTION OF METHYL RADICALS WITH CH₃CHO AND CH₃CDO
  作者：P. Ausloos、E. W. R. Steacie

  DOI：10.1139/v55-006

  日期：1955.1.1

  Azomethane has been photolyzed in the presence of CH₃CHO and CH₃CDO, and the results compared with the direct photolysis of the aldehydes. The activation energies found were 6.8 and 7.8 kcal./mole, respectively, for the reactions[Formula: see text]The results furnish evidence that only an acyl hydrogen is captured. Evidence has also been found for the occurrence of wall reactions and the disproportionation reaction[Formula: see text]

  甲基胺已在CH3CHO和CH3CDO存在下进行光解，结果与醛的直接光解进行了比较。找到的活化能分别为6.8和7.8 kcal/mol，反应为[Formula: see text]。结果表明只有酰基氢被捕获。还发现了壁反应和不均化反应的证据[Formula: see text]。

  spectrometer has been used to study the complex chemical kinetics involved in acetyl radical chemistry. This has involved direct monitoring of both acetyl and methyl radicals in the same experiment and over a variety of temperatures (263 ⩽T/K ⩽ 343) and total gas concentration (0.3 ⩽[M]/1019 molecule cm–3⩽ 2.7) conditions. These measurements have been complemented by a non-linear least-squares analysis

  分子调制光谱仪已用于研究乙酰基化学中涉及的复杂化学动力学。这涉及两个乙酰基和甲基的基团的直接监测在相同实验中和在各种温度下（263⩽ Ť / K⩽343）和总的气体浓度（0.3⩽[M] / 10 19分子厘米-32.7 2.7）条件。通过对实验数据进行非线性最小二乘法分析和简单的产品研究，对这些测量进行了补充。以此方式确定了四个反应的速率数据和乙酰基在223 nm处的吸收截面。基于Kassel积分的单分子速率理论已应用于压力依赖的自由基的形成和衰变，以提取T = 303和343 K处的速率常数的极限值。

  and pressure dependence of the decomposition of the trifluoroacetyl radical: CF3CO + M→CF3+CO + M (5′), have been studied by generating the radicals from the selective photolysis of azomethane in the presence of 1,1,1-trifluoroacetaldehyde over the temperature range 338–417 K. The rate constants of the decomposition reaction (k5′) have been measured relative to the radical combination reactions: CH3+CF3CO→CF3COCH3(6)

  [MoFe3S4]3+ core, perhaps accounting for the differences observed between the biological and abiological systems. 1,2-Dimethylhydrazine, a possible partially reduced intermediate in the reduction of cis-dimethyldiazene, was also shown to be reduced to methylamine. Interaction of methylamine with the Mo atom of the cubane was confirmed through the synthesis and structural characterization of (Et4N)

  报道了 (Et4N)2[(Cl4-cat)(CH3CN)MoFe3S4Cl3] 簇（Cl4-cat = 四氯儿茶酚酸盐）催化还原顺式二甲基二氮烯。与通过固氮酶的 Fe/Mo/S 中心还原顺式二甲基二氮不同，后者产生甲胺、氨和甲烷（后者来自 CN 键的还原），合成簇对顺式二甲基二氮的还原仅产生甲胺。在单独的实验中，表明 [MoFe3S4]3+ 核不会减少甲胺的 CN 键，这可能解释了生物系统和非生物系统之间观察到的差异。1,2-二甲基肼（一种可能在顺式二甲基二氮烯还原过程中被部分还原的中间体）也被证明可以还原为甲胺。通过 (Et4N)2[(Cl4-cat)(CH3NH2)MoFe3S4Cl3] 的合成和结构表征证实了甲胺与立方烷的 Mo 原子的相互作用。磷化氢抑制研究强烈表明 [MoFe3S...
