We report a gem-specific homo- and cross-dimerization of terminal alkynes catalyzed by a well-defined iron(II) complex containing Cp* and picolyl N-heterocyclic carbene (NHC) ligands, and featuring a piano-stool structure. This catalytic system requires no additives and is compatible with a broad range of substrates, including those with polar functional groups such as NH and OH.
我们报道了一种由含有 Cp*和吡啶基 N-杂环卡宾（NHC）配体的、结构明确的二价铁配合物催化的末端炔烃的同型和交叉二聚反应，该配合物具有钢琴凳结构。该催化体系无需添加助剂，并且与广泛的底物兼容，包括具有极性官能团如 NH 和 OH 的底物。
