hydroxylation, etc) of aromatic compounds in aqueous media. The first chemical step in these processes is monophotonic ionization of the aromatic compound in its lowest triplet state, followed by reaction of the radical cation with the nucleophile Quantum yields of photocyanation of 4-fluoro- and 4-chloroanisole indicate that in 99% (mole fraction) water virtually all triplets formed undergo electron
甲氧基在水性介质中的芳族化合物的光致亲核取代反应(氰化,羟基化等)中发挥活化和邻位/对位指导作用。这些过程中的第一步化学步骤是将芳族化合物的最低三重态单光子电离,然后使自由基阳离子与亲核试剂反应。4-氟和4-氯苯甲醚的光氰化产率表明,在99%(摩尔几乎所有形成的三胞胎都经历电子喷射。
