Nano copper ferrite catalyst is prepared and characterized by scanning electron microscopy, energy dispersive X-ray, X-ray diffraction, vibrational sample magnetometry, and Fourier transform infrared. The catalytic activity is probed for cross-dehydrogenative coupling of aromatic aldehydes in the presence of tert-butyl hydroperoxide as the oxidant. This catalytic protocol appears as a simple, rather
制备了纳米铜铁氧体催化剂,并通过扫描电子显微镜,能量色散X射线,X射线衍射,振动样品磁力分析和傅立叶变换红外光谱对其进行了表征。在叔丁基氢过氧化物作为氧化剂的存在下,检测芳香族醛的交叉脱氢偶联的催化活性。该催化方案看来是用于合成对称酸酐的简单,便宜,清洁且有效的实用策略,具有适当的效率(66%)。可以容易地通过外部磁体将催化剂与反应混合物分离,并在随后的反应中重复使用几次,而没有任何可衡量的效率损失。 图形摘要
