    • Oxidation of Alkynes via Catalytic Metal-Vinylidenes 

      Álvarez Pérez, Andrea; Saá Rodríguez, Carlos; Varela Carrete, Jesús Ángel (Thieme, 2020)
      Metal-vinylidenes, generated by treatment of terminal alkynes with transition metals, are very useful intermediates in modern synthetic chemistry as shown by the high number of transformations in which they are involved. ...
    • Palladium-Catalyzed Formal (4+2) Cycloaddition between Alkyl Amides and Dienes Initiated by the Activation of C(sp3)−H Bonds 

      Cendón Mariño, Borja; Font Molins, Marc; Mascareñas Cid, José Luis; Gulías Costa, Moisés (American Chemical Society, 2020)
      We report a formal (4+2) cycloaddition between alkyl-nosylamides and dienes enabled by a palladium-catalyzed activation of C(sp3)–H bonds beta to the amide group. This atom economical reaction, which proceeds under ...
    • Ruthenium-Catalyzed Oxidative Amidation of Alkynes to Amides 

      Álvarez Pérez, Andrea; Esteruelas Rodrigo, Miguel Ángel; Izquierdo, Susana; Varela Carrete, Jesús Ángel; Saá Rodríguez, Carlos (American Chemical Society, 2019)
      Complex CpRuCl(PPh3)2 catalyzes reactions of terminal alkynes with 4-picoline N-oxide and primary and secondary amines to afford the corresponding amides. The reactions occur in chlorinated solvent and aqueous medium, ...
