In the paper "Planar Geometry of 4-Substituted-2,2'-bipyridines Synthesized by Sonogashira and Suzuki Cross-Coupling Reactions", we report the synthesis, geometry and molecular arrangement in the crystals of two compounds, namely 4-(ferrocenylethynyl)-2,2'-bipyridine (I) and 4-ferrocenyl-2,2'-bipyridine (II) which were synthesized by the palladium catalyzed Sonogashira [5, 6] and Suzuki-Miyaura [7, 8] cross-coupling reactions. |
