Mg★ is an excellent in situ reducing agent for transition metal salts, giving highly reactive metal powders of Groups 8–12. In the presence of electron donor ligands, this reduction provides a useful one-step route to organotransition metal complexes. The application of 35 kHz ultrasound during the reaction improves the dispersity of the metal powders and enhances the yields of the complexes.
用少量蒽在THF中处理市售镁粉会生成高活性形式的镁(Mg★)。Mg★是一种出色的过渡金属盐原位还原剂,可产生8-12组的高反应性金属粉末。在电子给体配体的存在下,这种还原为有机过渡金属配合物提供了有用的一步法。反应过程中施加35 kHz超声波可改善金属粉末的分散性,并提高配合物的收率。
