4-Nitrobenzenesulfenate esters were used as precursors for the generation of alkoxyl radicals under laser flash photolysis conditions. The esters were efficiently cleaved using the Nd:YAG third harmonic (355 nm) to produce alkoxyl radicals and the 4-nitrobenzenethiyl radical. Rate constants for beta-scission and 1, 5-hydrogen abstraction reactions of alkoxyl radicals were measured.
4-硝基苯亚磺酸盐酯在激光闪光光解条件下被用作产生烷氧基自由基的前体。使用钕钇铝石榴石三倍频(355纳米)有效地裂解这些酯,以产生烷氧基自由基和4-硝基苯硫基自由基。测量了烷氧基自由基的β-断裂和1,5-氢提取反应的速率常数。
