虽然镁与蒽在THF中反应生成橙子、微溶的镁蒽是Ramsden在1965年发现的，1但镁蒽体系的化学直到20世纪80年代才开始发展，这是由镁蒽在温和条件下用于生成镁氢化催化剂体系而引发的。2.蒽镁化合物因其在合成中的广泛应用和催化金属镁反应的能力而引起人们的广泛兴趣。元素镁在催化量的蒽存在下可被氢化成高活性形式的氢化镁，是过渡金属盐的优良还原剂，并可在极其温和的条件下用于制备格氏化合物。活性MgH_2-Mg体系可通过镁的相转移催化作用进行化学合成，是一种优良的储氢和高温储热介质。本文将介绍这些主题，着重介绍最近的合成和催化应用。3
Although the reaction of magnesium with anthracene in THF to form the orange, sparingly solublemagnesium anthracene was discovered by Ramsden in 1965, 1 the chemistry of magnesium anthracene systems began to develop only in the 1980s, triggered by the applica-tion of magnesium anthracene to generate a catalyst system for the hydrogenation of magnesium under mild conditions. 2 Nowadays, magnesium anthracene com-pounds attract broad interest because of their versatile applications in synthesis and their ability to catalyze reactions of metallic magnesium. Elemental magnesium in the presence of a catalytic amount of anthracene can be hydrogenated to a highly reactive form of magnesium hydride, is an excellent reducing agent for transitionmetal salts, and can be used to prepare Grignard com-pounds under extremely mild conditions. The active MgH2-Mg system, accessible via phase-transfercatalysis of magnesium, can be applied for chemical syntheses and is an outstanding medium for hydrogen and high-temperature heat storage. An account of these topics, emphasizing recent synthetic and catalytic ap-plications, will be given here. 3
