本文报道过氧化环丙基甲酰(1)在不同类型溶剂中的化学行为。首先,我们建立了五个热解主要产物:环丙基甲酸环丙酯(4)、环丙基甲酸(5)、双环丙烷(6)、环丙烷(7)及二氧化碳的色谱定量分析方法,然后在不同类型的溶剂中测定1热分解产物的分布。结果表明,在非极性碳氢溶剂中,以自由基型的单分子均裂过程为主;在极性溶剂中则可能伴有诱导分解。我们的结果还表明,产物4,6,7主要生成于笼外,与文献报道的不同。更有趣的发现是,在HMPA中,1的分解可能主要是通过它与溶剂间的电子转移来实现的.
This paper reports the chemical behavior of cyclopropylformyl peroxide (1) in different types of solvents. First of all, we have established five main pyrolysis products: cyclopropyl cyclopropyl (4), cyclopropanecarboxylic acid (5), bicyclopropane (6), cyclopropane (7) and carbon dioxide chromatographic quantitative analysis, The distribution of thermal decomposition products is then determined in different types of solvents. The results showed that in the non-polar hydrocarbon solvent, the radical-based single molecule homo-cleavage process was dominant; in polar solvents, it was possible to induce decomposition. Our results also show that the products 4,6,7 are mainly generated outside the cage, which is different from those reported in the literature. A more interesting finding is that in HMPA, the decomposition of 1 may be mainly through its electron transfer with the solvent to achieve.
