amides – to Ni0 during Suzuki–Miyaura reactions can lead either to exquisite selectivity and enhanced reactivity, or to inhibition of the reaction. Aryl halides where the C–X bond is connected to the same π-system as an aldehyde or ketone undergo unexpectedly rapid oxidative addition to [Ni(COD)(dppf)] (1), and are selectively cross-coupled during competition reactions. When aldehydes and ketones are present

heterogeneous magnetic impressive nickel catalyst in which Fe3O4 nanoparticles have been coated with chitosan and decorated with nickelnanoparticles (Fe3O4@CS-Ni). This catalyst has been used for direct α-alkylation of aryl ketones with substituted benzyl alcohols through borrowing hydrogen and dehydrogenation mechanism that affords the corresponding α-benzyl ketones, with good to excellent yield. The
本文报道了一种非均相磁性镍催化剂,其中 Fe 3 O 4纳米粒子已涂有壳聚糖并用镍纳米粒子(Fe 3 O 4 @CS-Ni)进行装饰。该催化剂通过借氢和脱氢机理用于芳基酮与取代苯甲醇的直接α-烷基化反应,得到相应的α-苄基酮,具有良好至极好的收率。核壳形态已通过不同的分析技术进行确认,例如傅里叶变换红外 (FT-IR)、X 射线衍射 (XRD)、振动样品磁力计 (VSM)、扫描电子显微镜 (SEM)、透射电子显微镜 ( TEM)、SEM 映射、能量色散 X 射线 (EDX)、电感耦合等离子体 (ICP) 和热重分析 (TGA)。此外,催化剂可以通过使用外部磁场从反应混合物中回收并重复使用六个连续循环,而催化活性不会显着降低。
