Spiro butadienyl tetraorganocuprates 2a,b were synthesized from butadienyl dilithio reagent and 0.5 equiv of copper(I) salt. The oxidation reaction of 2a,b with I₂ or p-benzoquinone afforded the octatetraenyl organocopper(I) aggregate 3. This result demonstrated that the butadienyl skeletons rather than the copper(I) atom were oxidized preferentially. Single-crystal X-ray structural analysis revealed that the high-order organocuprates 2a,b have linear or zigzag polymeric structures, while the hexanuclear octatetraenyl organocopper(I) aggregate 3 consists of a core Cu₆ structure, which forms a regular hexagon.

通过螺旋丁二烯基有机锡的氧化形成六核辛基八烯基有机铜（I）聚集体。

由丁二烯基二硫代试剂和0.5当量的铜（I）盐合成了螺丁二烯基四有机癸酸酯2a，b。2a，b与I ₂或对苯醌进行氧化反应，得到辛三烯基有机铜（I）聚集体3。该结果表明，丁二烯基骨架而不是铜（I）原子被优先氧化。单晶X射线结构分析表明，高阶有机铜酸盐2a，b具有线性或锯齿形的聚合物结构，而六核八碳烯基有机铜（I）聚集体3由核心Cu ₆组成。 结构，形成规则的六边形。
