DOIAbstract
The products following Cl 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 characterized experimentally by FTIR spectroscopy assisted by ab initio calculations at the B3LYP/6-31++G(d,p) level. Relative rate techniques were used to measure k(Cl+FC(O)OOC(O)OCH3) = (4.0 ± 0.4) × 10-14 cm3 molecule-1 s-1 and k(Cl+FC(O)OOC(O)OCH2Cl) = (3.2 ± 0.3) × 10-14 cm3 molecule-1 s-1. When the reaction is...
