本文讨论了18种丙烯酸酯、甲基丙烯酸酯、巴豆酸酯、富马酸酯和马来酸酯的水合电子（e（aq）（-））和羟基自由基速率常数。常数接近扩散控制极限。k（e（aq）（-））和k（OH）的变化方向相反;如果k（e（aq）（-））很高，则k（OH）很小。这种倾向与e（aq）（-）的亲核性和OH的亲电性有关，尽管e（aq）（-）和OH的攻击位点不同：羰基与乙烯基。
The hydrated electron (e(aq)(-)) and hydroxyl radical rate constants with 18 acrylate-, methacrylate-, crotonate-, fumarate- and maleate esters are discussed. The constants approach the diffusion-controlled limit. k(e(aq)(-)) and k(OH) change in opposite direction; if k(e(aq)(-)) is high then k(OH) is small. This tendency is connected with the nucleophilic character of e(aq)(-) and the electrophilic character of OH, although the site of attack of e(aq)(-) and OH is different: carbonyl versus vinyl group.
