  Complexes of the Gilman Reagent with Double Bonds across the π–σ Continuum

  摘要：

  By using rapid injection NMR at low temperatures, a variety of pi-complexes of lithium dimethylcuprate(I) with C-C, C-N, and C-S double bonds have been prepared and characterized. Complexation is generally accompanied by large upfield changes in chemical shift for the substrate carbon atoms bonded to copper. In the case of alpha,beta-unsaturated carbonyl compounds, the changes for the carbonyl carbons are much smaller in magnitude, which is consistent with the usual eta(2) representation of these structures. It is possible for one ligand to displace another, and in this way an order of stability can be elucidated. Treatment of selected pi-complexes with chlorosilanes or cyanosilanes gives Cu-III intermediates.

• Minimization of Organocuprate Complexity through Self-Organization: Remarkable Orientation Effect in Mixed Cuprate π Complexes

  where to go: A powerful orientation effect has been observed in complexes of mixed organocuprates [RTRNTCuLi] and substrates with CC, CN, and CS double bonds (see scheme; Th=thienyl). The preferred geometry of the intermediate complex sets up the facile addition of RT to the double bond, rather than addition of the “dummy ligand”, RNT.

  他们“知道”去哪里：一个强大的取向效应在混合有机铜[R的复合物中观察到Ť ř NT CuLi]和底物使用C  C，C  N，和C  š双键（参见方案; TH =噻吩基）。中间配合物的优选几何形状建立了将R T容易地添加到双键中，而不是添加了“虚拟配体” R NT。
