Lithium tetramethylcuprate(III), Me4CuLi, the CuIII analog of the Gilman reagent, has been prepared in high yield from halo-Gilman reagents Me2CuLi·LiX (X = Cl, Br, I) and 2,3-dichloropropene and found to have surprising thermal stability. The cyano-Gilman reagent (X = CN) follows a different pathway.
四甲基
琥珀酸锂(III)Me4CuLi 是吉尔曼试剂的 CuIII 类似物,由卤代吉尔曼试剂 Me2CuLiÂ-LiX (X = Cl、Br、I)和
2,3-二氯丙烯高产制备而成,并发现其具有惊人的热稳定性。
氰基-吉尔曼试剂(X = CN)的制备途径与此不同。
