Organoselenides catalyze the oxidation of halides by H2O2. Furthermore, these selenides catalyze the transfer of oxidized halogens from N-halosuccinimides to olefins and ketones. Thus, organoselenides catalyze oxidative halogenation reactions including halolactonization, α-halogenation of ketones, and allylic halogenation. The ability of selenium to undergo reversible 2e− oxidation–reduction chemistry
有机硒化物通过H 2 O 2催化卤化物的氧化。此外,这些硒化物催化氧化的卤素从N-卤代琥珀酰亚胺向烯烃和酮的转移。因此,有机硒化物催化氧化卤化反应,包括卤代内酯化,酮的α-卤化和烯丙基卤化。硒的能力经历可逆2E -氧化-还原化学功能有助于卤化硒通过绑定卤中间体。
