Abstract

˙ CBr2CO2-and˙ CCl2CO2-radicals, generated upon one electron reduction of tribromo-and trichloro-acetic acids and˙ CF2CO2-radicals produced from difluoroacetic acid by reaction with˙ OH, exhibit optical absorptions in the UV with λmax at 290 nm (ε= 2580 dm3 mol-1 cm- 1), 330 nm (ε= 3000 dm3 mol-1 cm-1) and 310 nm (ε≈ 660 dm3 mol-1 cm-1), respectively. Mechanistically, the present report focuses on the free-radical-induced degradation of ...
