氯化镧(III)双(氯化锂)复合溶液是一种介导格利雅(Grignard)添加物的生化试剂。它也是金属交换反应的试剂,也是将有机金属化合物添加到位阻(可烯化或α,β-不饱和或不饱和)的酮或亚胺上的促进剂。 备注: 干的残留物是爆炸性的。 定期/蒸馏前检测过氧化物的生成。如有沉淀,请过滤后再使用。 应用 LaCl3•2LiCl 选择性 1,2-加成: 介导格氏试剂添加 金属交换反应试剂 用于在空间位阻、可烯醇化或 α,β-不饱和酮或亚胺中添加有机金属化合物的促进剂 Lanthanum(III) chloride bis(lithium chloride) complex solution is a biochemical that mediates Grignard additions. It is also a reagent for metal exchange reactions and a promoter for the addition of organometallic compounds to sterically hindered (enolizable or α,β-unsaturated) ketones or imines. Remarks: The dry residue is explosive. Peroxide formation is checked periodically/before distillation. If there is precipitation, please filter before use.
