Skeletal editing of pyridines through atom-pair swap from CN to CC
Nature ChemistrySkeletal editing is a straightforward synthetic strategy for precise substitution or rearrangement of atoms in core ring structures of complex molecules; it enables quick diversification of compounds that is not possible by applying peripheral editing ...

Two-Dimensional Molecular Patterning by Surface-Enhanced Zn-Porphyrin Coordination [PDF]
, 2009 In this contribution, we show how zinc-5,10,15,20-meso-tetradodecylporphyrins (Zn-TDPs) self-assemble into stable organized arrays on the surface of graphite, thus positioning their metal center at regular distances from each other, creating a molecular ...

Recent Strategies in the Nucleophilic Dearomatization of Pyridines, Quinolines, and Isoquinolines
Chemical ReviewsDearomatization reactions have become fundamental chemical transformations in organic synthesis since they allow for the generation of three-dimensional complexity from two-dimensional precursors, bridging arene feedstocks with alicyclic structures. When
