TMPLi (TMP=2,2,6,6-四甲基哌啶酯)在Et2O存在下与CuI盐反应生成二聚体[{(TMP)2Cu(X)Li2(OEt2)}2] (X=CN,卤化物)。相比之下,使用DMPLi (DMP=顺式2,6-二甲基哌啶酯)给出了前所未有的结构基序;[{(DMP) 2 culi (OEt2)} 2 lix] (X =卤)。这一配方提出了迄今为止尚未探索的吉尔曼型碱基原位形成的途径,这些碱基在定向正位铜化中具有已证实的反应性。
TMPLi (TMP=2,2,6,6-tetramethylpiperidide) reacts with CuI salts in the presence of Et2O to give the dimers [{(TMP)2Cu(X)Li2(OEt2)}2] (X=CN, halide). In contrast, the use of DMPLi (DMP=cis-2,6-dimethylpiperidide) gives an unprecedented structural motif; [{(DMP)2CuLi(OEt2)}2LiX] (X=halide). This formulation suggests a hitherto unexplored route to the in situ formation of Gilman-type bases that are of proven reactivity in directed ortho cupration.
