Water: The Ideal Hydrogen‐Atom Source in Free‐Radical Chemistry Mediated by TiIII and Other Single‐Electron‐Transfer Metals?
Juan M. Cuerva,Araceli G. Campaña,José Justicia,Antonio Rosales,Juan L. Oller-López,Rafael Robles,Diego J. Cárdenas,Elena Buñuel,J. Enrique Oltra +8 more
TL;DR: Solid evidence is shown to show that water really can act as a complete hydrogen-atom source rather than as a simple proton donor for radical reductions mediated by Ti and, presumably, other metals that react by single-electron transfer.
Journal ArticleDOI
Undecabenzo[7]superhelicene: A Helical Nanographene Ribbon as a Circularly Polarized Luminescence Emitter
Carlos Cruz,Silvia Castro-Fernández,Ermelinda M. S. Maçôas,Juan M. Cuerva,Araceli G. Campaña +4 more
TL;DR: The synthesis and characterization of an enantiopure superhelicene nanographene is reported in which two saddle-shaped and one planar hexabenzocoronene (HBC) units are arranged in a helicoidal shape to form an undecabenzo[7]carbohelicenes, the first fully π-extended [7] helicene.
Journal ArticleDOI
7-endo radical cyclizations catalyzed by titanocene(III). Straightforward synthesis of terpenoids with seven-membered carbocycles.
José Justicia,Juan L. Oller-López,Araceli G. Campaña,J. Enrique Oltra,Juan M. Cuerva,Elena Buñuel,Diego J. Cardenas +6 more
TL;DR: Theoretical and experimental evidence is provided in support of a plausible mechanism, which may rationalize the preference for the unusual 7-endo cyclization mode shown by radicals with substitution patterns characteristic of the linalyl, nerolidyl, and geranyl linalsyl systems.
Journal ArticleDOI
Titanocene‐Catalyzed Cascade Cyclization of Epoxypolyprenes: Straightforward Synthesis of Terpenoids by Free‐Radical Chemistry
José Justicia,Antonio Rosales,Elena Buñuel,Juan L. Oller-López,Monica V. Valdivia,Ali Haidour,J. Enrique Oltra,Alejandro F. Barrero,Diego J. Cárdenas,Juan M. Cuerva +9 more
TL;DR: Both theoretical and experimental evidence suggests that this titanocene-catalyzed cascade cyclization of epoxypolyenes takes place in a nonconcerted fashion via discrete carbon-centered radicals, and its end step can easily be controlled to give exocyclic double bonds by simply excluding water from the medium.
Journal ArticleDOI
Understanding the Exceptional Hydrogen-Atom Donor Characteristics of Water in TiIII-Mediated Free-Radical Chemistry
Miguel Paradas,Araceli G. Campaña,Tania Jiménez,Rafael Robles,J. Enrique Oltra,Elena Buñuel,José Justicia,Diego J. Cárdenas,Juan M. Cuerva +8 more
TL;DR: This work demonstrates that the efficiency of titanocene(III) aqua complexes as an unique class of HAT reagents is based on two key features: excellent binding capabilities of water toward titanocene (III) complexes and a low activation energy for the HAT step.
