Cul-catalysed reactions between halide complexes of Fe, Mo, W or Pt and an excess of buta-1,3-diyne in the presence of diethylamine lead to the formation of buta-1,3-diynyl compounds; elaboration of the diynyl ligand is achieved by replacement of H by either non-metal or metal groups, by coordination to the CC triple bonds and by incorporation of the terminal C atoms into clusters with consequent electronic rearrangement along the C4 chain.
在
二乙胺存在下,Fe、Mo、W 或 Pt 的卤化物络合物与过量的丁-1,3-二炔发生秆催化反应,生成丁-1,3-二炔化合物;通过非
金属或
金属基团取代 H、与 CC 三键配位以及将末端 C 原子并入簇中从而沿 C4 链进行电子重排,实现二炔
配体的精细化。
