Hazard Class4.3
  • ⑴. 也称异丁基锂,无色或微黄色透明液体。 ⑵. 锂化剂。异戊二烯、丁二烯的聚合。制备氢化锂、四氢呋喃、苄基锂化合物。 ⑶. 相对于正丁基锂而言,异丁基锂的碱性更强,金属化活性更高,亲核性更差。因此,对于正丁基锂无法作用的弱酸性底物的锂化反应如制备芳基、乙烯基、和烯丙基锂试剂时、以及在需要弱亲核性锂化试剂时,异丁基锂是不错的选择。 △与正丁基锂相似,异丁基锂参与的反应也应在给电子溶剂如乙醚、THF和二甲基乙烷(DME)中进行,目的是促进低阶有机锂的聚集。与三级多胺配体如HMPA、TMEDA或DABCO联合 有机催化反应
  • Limited shelf life. During storage white precipitate of LiH may form.
  • Widely used base for directed metallation reactions. For use in combination with TMEDA for ortho-lithiation of an N,N-dialkyl benzamide, and of 1-Boc-indoline at the 7-position, see: Org. Synth. Coll., 8, 124, 559 (1998).
