Abstract
[CpIr(H)(bpym)]+ and [CpIr(H)(bpy)]+ are the first examples of iridium based catalysts for the aerobic oxidation of alcohols; the catalytic cycle proceeds via acidic hydrides. Deprotonation of the hydride leads to a highly oxygen sensitive Ir I species that regenerate the Ir III complexes upon oxidation with dioxygen.
摘要
[CpIr(H)(bpym)]⁺ 和 [CpIr(H)(bpy)]⁺ 是用于醇类有氧氧化的铱基催化剂的首个实例；催化循环通过酸性氢化物进行。氢化物的去质子化导致一种对氧高度敏感的 Ir I 物种，该物种在与氧气氧化时会再生 Ir III 配合物。
