Structure 1 is the major component obtained by the reaction of two equivalents of RLi and one equivalent of CuCN; other proposed structures can now be ruled out on the basis of N NMR spectroscopic and theoretical studies. Thus, these useful synthetic reagents should be considered as cyano-Gilman reagents R CuLi⋅LiCN and not "higher order cyanocuprates" R Cu(CN)Li .
结构1是由两当量的RLi与一当量的CuCN反应得到的主要成分；根据氮核磁共振光谱和理论研究，现在可以排除其他提出的结构。因此，这些有用的合成试剂应被视为氰基吉尔曼试剂RCuLi⋅LiCN，而不是“高阶氰基铜酸盐”RCu(CN)Li 。
