(NHPI) catalysts designed for the aerobic oxidation of cumene in solvent-free conditions was synthesized and tested. The specific strategy proposed for the introduction of lipophilic tails on the NHPI moiety leads to lipophilic catalysts that—while completely preserving the activity of the precursor—allow the catalytic oxidation to be conducted in neat cumene, for the first time. The corresponding cumyl
一类新的亲脂氮合成并测试了设计用于无溶剂条件下异丙基苯的好氧氧化的-羟基邻苯二甲酰亚胺(NHPI)催化剂。提出的在NHPI部分上引入亲脂性尾巴的特定策略导致了亲脂性催化剂,该催化剂虽然完全保留了前体的活性,但首次允许在纯异丙基异丙苯中进行催化氧化。在温和的条件下,可获得高产率(28-52%)和高选择性(95-97%)的相应的氢过氧化枯基。重要的是,不再需要极性溶剂的存在以保证催化剂完全溶解。另一方面,
