    Transition metal-free controlled synthesis of bis[(trifluoromethyl)sulfonyl]ethyl-decorated heterocycles
    (Organic Chemistry Frontiers, 2018) Almendros Requena, Pedro; Yanai, Hikaru; Hoshikawa, Shoki; Aragoncillo Abanades, Cristina; Lázaro Milla, Carlos; Toledano-Pinedo, Mireia; Matsumoto, Takashi; Alcaide Alañón, Benito
    Several heterocycles reacted with shelf-stable 2-(2-fluoropyridinium-1-yl)-1,1-bis[(trifluoromethyl)sulfonyl] ethan-1-ide, a latent Tf2CvCH2 source, to give rise in a mild and controllable way to adducts via direct C–H bis[(trifluoromethyl)sulfonyl]ethylation reactions. This metal- and irradiation-free protocol is convenient. Besides, the volatile side-product 2 fluoropyridine can be smoothly eliminated under vacuum, which facilitates purification. The substrate scope survey discloses that exquisite chemo- and regioselectivities are achieved in a variety of heterocyclic systems. Of particular interest are the late-stage structural modification of known pharmaceuticals, such as the marketed drugs Phenazone (Antipyrine) and Edaravone, and the development of a water soluble fluorescent dye.

    A facile synthesis of blue luminescent [7]helicenocarbazoles bBased on golcatalyzed rearrangement‐iodonium migration and Suzuki–Miyaura benzannulation reactions
    (Chemistry a European Journal, 2018) Alcaide Alañón, Benito; Almendros Requena, Pedro; Aragoncillo Abanades, Cristina; Busto García, Benjamín Eduardo; López‐Calixto, Carmen ; Liras, Marta; Peña O'Shea, Víctor de la; García‐Sánchez, Alba; Stone, Hannah
    New azahelicenes having interesting photophysical properties have been prepared in a four‐step sequence. These [7]helicenocarbazoles are efficient blue luminophores, demonstrating the utility of gold catalysis in the preparation of advanced materials.
