atom initiated reactions of FC(O)OOC(O)OCH3 in 50–760 Torr of N2 at 296 K were investigated using FTIR. Reaction of Cl atoms with methyl fluoroformyl peroxycarbonate proceeds mainly via attack at the methyl group, forming FC(O)OOC(O)OCH2• radicals. Further reaction of this kind of radical with Cl2 forms three new compounds: FC(O)OOC(O)OCH2Cl, FC(O)OOC(O)OCHCl2, and FC(O)OOC(O)OCCl3, whose existence was
使用FTIR研究了在296 K下N 2在50–760 Torr中FC(O)OOC(O)OCH 3由Cl原子引发的反应产物。Cl原子与氟代过氧碳酸甲酯的反应主要通过对甲基的攻击而进行,从而形成FC(O)OOC(O)OCH 2 •自由基。这种自由基与Cl 2的进一步反应形成三个新化合物:FC(O)OOC(O)OCH 2 Cl,FC(O)OOC(O)OCHCl 2和FC(O)OOC(O)OCCl 3,通过FTIR光谱通过B3LYP / 6-31 ++ G(d,p)的从头算计算辅助实验表征了其存在。相对速率技术用于测量k (Cl + FC(O)OOC(O)OCH3)=(4.0±0.4)×10 –14 cm 3分子–1 s –1和k (Cl + FC(O)OOC(O)OCH2Cl) =(3.2±0.3)×10 –14 cm 3分子–1 s – 1。当反应在氧气的存在下进行时,形成氯化过氧化物的途径被
