标题:铜助催化剂调节自由基反应生成用于 α-卤代酮的选择性异相光合作用
摘要:α-卤代酮是合成化学和制药应用的重要前体;然而,它们的生产在很大程度上依赖于传统的合成方法,即对有毒且对环境有风险的酮进行卤化.在这里,我们报告了在温和反应条件下使用铜改性石墨碳氮化物 (Cu-c 3 N 4)从芳香烯烃生产 α-卤代酮的多相光合策略.通过使用 Nix 2(X = Cl,Br)作为卤源,在可见光照射下,以大气为氧化剂,可以合成一系列α-卤代酮.与原始的氮化碳相比,添加cu作为助催化剂提供了适度的卤素自由基反应生成速率和分子氧选择性还原为• Ooh自由基,从而导致对α-卤代酮的高选择性.cu-C 3 N 4还表现出高稳定性和多功能性,使其成为太阳能驱动合成应用的有前途的候选者.
