Abstract
[GRAPHICS] 4-Nitrobenzenesulfenate esters were used as precursors for the generation o f alkoxyl radicals under laser flash photolysis conditions. The esters were efficiently cleaved using the Nd:YAG third harmonic (355 nm) to produce al koxyl radicals and the 4-nitrobenzenethiyl radical. Rate constants for beta -scission and 1,5-hydrogen abstraction reactions of alkoxyl radicals were m easured.
