摘要

Alkylperoxyl radicals are intermediates in the oxidation of hydrocarbons. The reactive nature of these intermediates, however, has made them elusive to direct observation and isolation. We have employed ion trap mass spectrometry to synthesize and characterize 4- carboxylatocyclohexyl radical anions (• C6H10− CO2−) and observe their reactivity in the presence of dioxygen. The resulting reaction is facile (k= 1.8× 10− 10 cm3 molecule− 1 s− ...
