(NHC)M Cores as Catalysts for the Olefin Aziridination Reaction (M= Cu, Ag, Au): Evidencing a Concerted Mechanism for the Nitrene Transfer Process
Pérez Ruíz, Jorge; Díaz Requejo, María Mar
; Pérez Romero, Pedro José (American Chemical Society, 2022-11-28)
Complexes [(NHC)MCl] (M = coinage metal) have been evaluated as catalyst for the olefin aziridination reaction using PhI=NTs as nitrene source, with moderate to high activity being found depending of the metal and the ... -
Polipirazolilborato complejos de cobre (I) como catalizadores en reacciones de transformación de olefinas en ciclopropanos, aziridinas y epóxidos
Díaz Requejo, María Mar (2000)
1. Preparación de los pre-catalizadores. La reacción, a baja temperatura, de CuI y la sal potásica del ligando dihidrobispirazolilborato (KBp) en acetonitrilo (ec 1) permite el aislamiento de un sólido de color blanco ... -
Pyrrole Functionalization by Copper‐Catalyzed Nitrene Transfer Reactions
Rodríguez, Anabel M.; Rodríguez, Manuel R.; Díaz Requejo, María Mar; Pérez Romero, Pedro José (Wiley-VCH Verlag, 2020-03)
The catalytic functionalization of pyrroles by incorporation of a nitrene group is reported. The Cα‐H bond of 1H‐pyrrole is amidated upon the formal insertion of the NTs (Ts=p‐toluenesulfonyl) group catalyzed by TpBr3Cu(NCMe) ... -
Reacciones de transferencia de nitrenos catalizada por complejos de cobre y plata : aplicaciones sintéticas y estudios mecanísticos
Maestre Cera, Lourdes (Universidad de Huelva, 2014)
Esta Tesis Doctoral tiene como denominador común la reacción de transferencia de un ligando nitreno desde un complejo metálico de cobre o plata a distintos sustratos orgánicos. La agrupación metal-nitreno se genera in situ ... -
Silver-Catalyzed C-C Bond Formation between Methane and Ethyl Diazoacetate in Supercritical CO2
Caballero Bevia, Ana; Despagnet-Ayoub, Emmanuelle; Díaz Requejo, María Mar; Díaz Rodríguez, Alba; González Núñez, María Elena; Mello, Rosella; Muñoz, Bianca K.; Ojo, Wilfried-Solo; Asensio, Gregorio; Etienne, Michel; Pérez Romero, Pedro José (American Association for the Advancement of Science, 2011-05)
Even in the context of hydrocarbons’ general resistance to selective functionalization, methane’s volatility and strong bonds pose a particular challenge. We report here that silver complexes bearing perfluorinated ... -
Sistemas catalíticos basados en Cu y Ag para el desarrollo de nuevas reacciones de transferencia de grupo nitreno
(Universidad de Huelva, 2021)Esta Tesis Doctoral versa sobre el estudio de sistemas catalíticos basados en cobre y plata para la transferencia de grupo nitreno a distintos sustratos orgánicos. Se encuentra estructurada en una Introducción General, ... -
The TpxM Core in Csp3–H Bond Functionalization Reactions: Comparing Carbene, Nitrene, and Oxo Insertion Processes (Tpx = Scorpionate Ligand; M = Cu, Ag)
Díaz Requejo, María Mar; Pérez Romero, Pedro José (Wiley, 2020-03)
A comparison between three TpxM‐catalyzed (Tpx = scorpionate ligand; M = Cu, Ag) reactions leading to the functionalization of non‐activated, alkane Csp3–H bonds by carbene, nitrene or oxo insertion is presented. Analogies ... -
Trispyrazolylborate Ligands Supported on Vinyl Addition Polynorbornenes and Their Copper Derivatives as Recyclable Catalysts
Molina de la Rorre, Jesús A.; Pérez Ortega, Ignacio; Beltrán Martín, Álvaro; Rodríguez, Manuel R.; Díaz Requejo, María Mar; Pérez Romero, Pedro José; Albéniz, Ana C. (Wiley, 2019)
Polynorbornenes prepared by vinyl addition polymerization and bearing pendant alkenyl groups serve as skeletons to support trispyrazolylborate ligands (Tp(x)) built at those alkenyl sites. Reaction with CuI in acetonitrile ...
