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.
我们报告了特定的末端炔烃的宝石特异性同二聚和交叉二聚化反应,该炔烃由定义明确的铁(II)配合物催化,该配合物含有Cp *和甲基吡啶基N-杂环卡宾(NHC)配体,并且具有钢琴凳结构。该催化体系不需要添加剂,并且可与多种底物兼容,包括具有极性官能团(例如NH和OH)的底物。
