Iron‐Catalyzed gem‐Specific Dimerization of Terminal Alkynes

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 ra...

Description
Summary: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. A real gem: Iron‐catalyzed gem‐specific homo‐ and cross‐dimerization of terminal alkynes was realized with a well‐defined piano‐stool iron(II) complex featuring Cp* and picolyl NHC ligands. The 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.
