产品应用

  • ⑴.无色液体，高度易燃。引起严重灼伤。吞食可能造成肺部损伤。蒸汽可能引起困倦和眩晕。
  • ⑵.主要用作精细化学品的还原剂和氢铝化剂。
  • ⑶.具有强烈的吸湿性，对空气和湿气敏感，遇水会发生激烈反应放出氢气。
  • ⑷.四氢呋喃不适宜作溶剂，因为两者反应生成配位化合物。二异丁基氢化铝是一种新型金属有机化合物，可使酮、羧酸、酯选择性还原成相应的醛或者醇。
  • Used in Pd-catalyzed reductive debromination of secondary alkyl bromides. O-Debenzylation and ring opening of perbenzylated furanosides. Convenient in situ generation of HZrCp2Cl from ZrCp2Cl2 and DIBAL-H.
