镁金属化合物催化性能的研究

摘 要

镁处于元素周期表中第二主族，碱土金属元素的价态通常为 0 价和＋2 价， 2007 年, Cameron Jones等首先成功合成了稳定的 1价镁金属化合物。随后，一系列稳定的金属镁化合物被合成出来，并在催化方面得到了一定的应用。醛和酮还原为伯醇和仲醇是有机化学中的重要反应之一。布朗与1939年发现未催化乙硼烷可还原醛酮，从此之后，开始了对选择性差的硅烷和硼烷氢化物和使用条件苛刻的金属氢化物催化过程的研究。

Abstract

Magnesium is in the second main group of the periodic table. Alkaline earth metal elementsrsquo; valence state usually is zero or two price. In 2007, Dr. Cameron Jones first successfully synthesized a stable one price magnesium metal compound. Subsequently, a series of stable magnesium compounds have been synthesized and used in catalysis.The reduction of aldehydes and ketones to primary and secondary alcohols is one of the most important transformations in organic chemistry. Brownrsquo;s discovery of uncatalysed diborane reduction of aldehydes and ketones in 1939, thus, served to direct research from harsh metal hydride reagents with poor selectivity towards catalytic processes using milder silane and borane hydride sources.

Key Words: magnesium, catalyst, hydroboration
