    • closedAccess   Anion-Responsive Diguanidinium-Based Chiral Organogelators 

      Valero, Julián; Escuder, Beatriu; Miravet, Juan; Mendoza, Javier de Wiley (2012-10)
      The chiral bicyclic diguanidinium chloride 1 forms gels in aromatic apolar solvents. The gels were characterized at different levels of organization, from the macroscopic to the molecular level by using microscopy, ...

    • closedAccess   Enantiopure triazolium salts. Chemoenzymatic synthesis and applications in organocatalysis 

      Luis, Santiago V.; Garcia-Verdugo, Eduardo; Ríos-Lombardía, Nicolás; Porcar Garcia, Raul; Busto, Eduardo; Alfonso Rodríguez, Ignacio; Montejo Bernardo, José; Garcia-Granda, Santiago; Gotor Fernández, Vicente Wiley-VCH Verlag GmbH & Co. KGaA (2011-10-14)
      A novel family of triazolium salt enantiomers has been efficiently synthesized by combining chemical and biocatalytic methods. The stereoselective action shown by hydrolytic enzymes led to the design of simple and general ...

    • openAccess   Enantioselective synthesis of tungsten trimetallic cluster chalcogenides 

      Guillamón, Eva; Llusar, Rosa Elsevier (2015-01)
      Excision of {W3Q7Br4}n (Q = S, Se) of polymeric phases using chiral diphosphines is a general procedure to synthesize optically pure trinuclear clusters. Chiral transfer from the enantiomerically pure diphosphines ...

    • closedAccess   Self-Assembly Studies of a Chiral Bisurea-Based Superhydrogelator 

      Rodríguez Llansola, Francisco; Hermida Merino, Daniel; Nieto Ortega, Belén; Ramírez, Francisco J.; López Navarrete, Juan T.; Casado, Juan; Hamley, Ian W.; Escuder, Beatriu; Hayes, Wayne; Miravet, Juan Wiley (2012-11)
      A chiral bisurea-based superhydrogelator that is capable of forming supramolecular hydrogels at concentrations as low as 0.2 mM is reported. This soft material has been characterized by thermal studies, rheology, X-ray ...

    • closedAccess   Synthesis of Heterodimetallic Iridium–Palladium Complexes Containing Two Axes of Chirality: Study of Sequential Catalytic Properties 

      Sabater López, Sara; Mata Martínez, Jose A; Peris, Eduardo WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim (2013-09)
      The reaction of [Cp*Cl2Ir(triazolium-ylidene)]BF4 (Cp* = pentamethylcyclopentadienyl) with chiral orthometalated palladium dimers results in facile bridge splitting to afford heterodimetallic Ir–Pd* complexes. The structural ...
