The gas phase reactions of the bridgehead 3-carboxylato-1-adamantyl radical anion were observed with a series of neutral reagents using a modified electrospray ionisation linear ion trap mass spectrometer. This distonic radical anion was observed to undergo processes suggestive of radical reactivity including radical-radical combination reactions, substitution reactions and addition to carbon-carbon
使用改进的电喷雾电离线性离子阱质谱仪,用一系列中性试剂观察了桥头3-羧基--1-金刚烷基自由基阴离子的气相反应。观察到该二元自由基阴离子经历暗示自由基反应性的过程,包括自由基-自由基结合反应,取代反应和碳-碳双键的加成。测量了3-羧基1-金刚烷基自由基阴离子与以下试剂的反应速率常数(单位为10(-12)cm(3)分子(-1)s(-1)):(18)O (2)(85 +/- 4),NO(38.4 +/- 0.4),I(2)(50 +/- 50),Br(2)(8 +/- 2),CH(3)SSCH( 3)(12 +/- 2),苯乙烯(1.20 +/- 0.03),CHCl(3)(H抽象0.41 +/- 0.06,Cl抽象0.65 +/- 0.1),CDCl(3)(D抽象0.035 + /-0.01,Cl抽象度0.723 +/- 0.005),烯丙基溴(Br提取0.53 +/- 0.04,烯丙基化0
