應用

镁(粉)可用作还原剂以合成:
  • 钛合金氢化物粉末,通过氢气气氛下还原升级钛渣(UGS)。      
  • 通过球磨法从赤铁矿(α-Fe2O3)制备超细金属铁(bcc-Fe)粉。

还可用作还原剂,用于钌(III)络合物催化原子转移自由基加成(ATRA)和环化(ATRC)反应。镁不能产生自由基,但能生成和再生具有催化活性的钌(II)。

A new catalytic procedure for atom-transfer radical addition (ATRA) and cyclization (ATRC) reactions is described. The combination of the ruthenium(III) complex [RuCl(2)Cp*(PPh3)] (Cp*: pentamethylcyclopentadienyl) with magnesium allows these reactions to be performed under mild conditions with high efficiency.
