strong Lewis acid and photoredox sites in engineered mesopores. Al-MOF (1) with mixed 2,2'-bipyridyl-5,5-dicarboxylate (dcbpy) and 1,4-benzenediacrylate ligands was oxidized with ozone and then tiflated to generate strongly Lewis acidic Al-OTf sites in the mesopores, followed by the installation of [Ir(ppy)2(dcbpy)]+ (ppy = 2-phenylpyridine) sites to afford 1-OTf-Ir with both Lewis acid and photoredox
在这里,我们通过在工程介孔中安装强路易斯酸和光氧化还原位点来报告模拟酶的金属有机框架 (MOF) 1-OTf-Ir 的设计。具有混合 2,2'-联吡啶-5,5-二羧酸酯 (dcbpy) 和 1,4-苯二丙烯酸酯配体的 Al-MOF (1) 用臭氧氧化,然后 tiflated 以在介孔中生成强路易斯酸性 Al-OTf 位点,然后安装 [Ir(ppy)2(dcbpy)]+ (ppy = 2-苯基吡啶) 位点以提供具有路易斯酸和光氧化还原位点的 1-OTf-Ir。1-OTf-Ir 有效地催化 N-羟基邻苯二甲酰亚胺酯或芳基溴甲基酮与乙烯基或炔基氮杂芳烃的还原交叉偶联,以提供新的氮杂芳烃衍生物。1-OTf-Ir 能够催化合成抗胆碱能药物苯那敏和氯苯那敏。
