Abstract

The ozonolysis reaction of trans-2-hexenal was studied theoretically on the basis of highly accurate CCSD(T)-F12b/AVTZ energy values obtained in M06-2X/AVTZ preoptimized nuclear configurations. The kinetics was modeled with the help of the master equation solver MESMER. Apart from the expected stable oxidation products 1-butanal (17%) and glyoxal (35%), a secondary ozonide is formed on the glyoxal channel, which is the principal first-generation product (49%). It is further shown that glyoxal is created on two competing pathways, one of which leads to simultaneous production of the ester propylformate (18%). The inclusion of all of these mechanisms explains the experimental findings and identifies for the first time the origin of the experimental carbon deficit.

第一代反式-2-己烯醛臭氧分解产物:机理的新探讨。
根据在 M06-2X/AVTZ 预优化核配置中获得的高精度 CCSD(T)-F12b/AVTZ 能量值,对反式-2-己烯醛的臭氧分解反应进行了理论研究。动力学模型是在主方程求解器 MESMER 的帮助下建立的。除了预期的稳定氧化产物 1-丁醛(17%)和乙二醛(35%)外,乙二醛通道上还形成了二级臭氧,这是主要的第一代产物(49%)。研究进一步表明,乙二醛是通过两条相互竞争的途径产生的,其中一条途径会同时产生丙基甲酸酯(18%)。所有这些机制都解释了实验结果,并首次确定了实验性碳赤字的来源。
