Nano‐ferrite‐supported Cu nanoparticles (Fe‐dopamine‐Cu NPs) catalyzed anti‐Markovnikov‐selective hydroboration of alkenes with B2pin2 is reported under mild reaction conditions. This protocol can be applied to a broad range of substrates with high functional group compatibility. In addition, we demonstrated the use of Fe‐dopamine‐Cu NPs as a catalyst for the β‐borylation of α,β‐unsaturated ketones and ester, providing
据报道,在温和的反应条件下,纳米铁氧体负载的铜纳米颗粒(Fe-多巴胺-Cu NPs)用B 2 pin 2催化烯烃的反Markovnikov选择性硼氢化。该协议可应用于具有高官能团兼容性的多种基材。此外,我们证明了使用铁多巴胺-铜纳米颗粒作为α,β-不饱和酮和酯的β-硼化催化剂,可提供高达98%的烷基硼酸酯。对于这两个系统,在多达五个反应运行中,可磁循环使用的催化剂的再利用都不会导致活性的显着降低。
