In the presence of catalytic amounts of magnetite nanopowder, mixtures of aromatic and aliphatic carboxylic acids are converted selectively into the corresponding aryl alkyl ketones. As by‐products, only carbon dioxide and water are released. This catalytic cross‐ketonisation allows the regioselective acylation of aromatic systems and, thus, represents a sustainable alternative to Friedel–Crafts acylations
在催化量的磁铁矿纳米粉的存在下,芳族和脂族羧酸的混合物被选择性地转化为相应的芳基烷基酮。作为副产品,仅释放二氧化碳和水。这种催化的交叉酮化可以使芳族系统进行区域选择性酰化,因此,它是Friedel-Crafts酰化反应的可持续替代方案。
