and spectroscopic (ICP-EOS, XPS) analysis tools. The metal composite was effectively employed in the unprecedented heterogeneously Ni-assisted cross-coupling reaction of aryl/vinyl iodides and thiocarboxylates. A range of sulfur-containing aryl as well as vinyl derivatives (15 examples) was achieved in high yields (up to 82%), under mild reaction conditions, and with wide functional group tolerance
制备了一种新型的无配体镍纳米颗粒支撑在 rGO 上(平均粒径分布 d = 9 ± 3 nm),并通过形态学 (Fe-SEM)、结构学 (P-XRD、HR-TEM) 和光谱学进行了充分表征(ICP-EOS, XPS) 分析工具。该金属复合物有效地用于芳基/乙烯基碘化物和硫代羧酸盐的前所未有的非均相 Ni 辅助交叉偶联反应。在温和的反应条件和广泛的官能团耐受性下,以高产率(高达 82%)获得了一系列含硫芳基和乙烯基衍生物(15 个实例)。
