    Synthesis and reactivity of a trigonal porous nanographene on a gold surface
    (Chemical Science, 2019) Zuzak, Rafal; Pozo, Iago; Engelund, Mads; Garcia-Lekue, Aran; Vilas-Varela, Manuel; Alonso Gómez, José Miguel; Szymonski,Marek; Guitián, Enrique; Pérez, Dolores; Godlewski,Szymon; Peña, Diego
    The synthesis of porous nanographenes is a challenging task for solution chemistry, and thus, on-surface synthesis provides an alternative approach. Here, we report the synthesis of a triporous nanographene with 102 sp2 carbon atoms by combining solution and surface chemistry. The carbon skeleton was obtained by Pd-catalyzed cyclotrimerization of arynes in solution, while planarization of the molecule was achieved through two hierarchically organized on-surface cyclodehydrogenation reactions, intra- and inter-blade. Remarkably, the three non-planar 14]annulene pores of this nanographene further evolved at higher temperatures showing interesting intra-porous on-surface reactivity.

    Palladium-catalyzed cocyclotrimerization of arynes with a pyramidalized alkene
    (Chemical Communications, 2018) Alonso Gómez, José Miguel; Quiroga, Sabela; Codony, Sandra; Turcu, Andreea ; Barniol-Xicota, Marta; Pérez, Dolores; Guitián, Enrique; Vázquez, Santiago; Peña, Diego
    A pyramidalized alkene and diverse arynes are generated in the presence of a Pd-catalyst to afford [2+2+2] cocycloaddition products. The metal-catalyzed 2+2+2] cocycloaddition of arynes with pyramidalized alkenes is presented. The generation of a highly reactive pyramidalized alkene in the presence of a large excess of in situ-produced arynes led to the corresponding cocyclotrimerization (1 : 2)-adducts in good yields, establishing the first example of a palladium-based reaction of a pyramidalized alkene.
