Cyclopentannulated Decacyclenes as Carbon‐Based Multistage Electron Acceptors
Chemistry – An Asian Journal, EarlyView.A series of cyclopentannulated decacyclenes were synthesized in a modular approach. Subsequent cyclization allowed the expansion of the π‐system. The carbon‐based compounds undergo up to six reversible reductions within an impressively narrow potential range between −1.45 and −2.86 V under electrochemical conditions.

Development of Copper Catalysts Supported on Graphite to Produce Butenes by Acetylene Dimerization
ChemCatChem, EarlyView.The incorporation of copper nanoparticles on the graphite surface leads to the development of catalytic materials capable of selectively hydrogenating acetylene into ethylene and promoting the dimerization reaction to produce butenes. The catalytic properties can be modulated depending on the metal precursor employed. Based on our experimental data, it
