A Quantitative Model for Alkane Nucleophilicity Based on C−H Bond Structural/Topological Descriptors
Besora, María; Olmos Verge, Andrea
; Noverges, Bárbara; Asensio, Gregorio; Caballero Bevia, Ana; Maseras, Feliu; Pérez Romero, Pedro José (Wiley, 2020)
A first quantitative model for calculating the nucleophilicity of alkanes is described. A statistical treatment was applied to the analysis of the reactivity of 29 different alkane C−H bonds towards in situ generated metal ... -
Catalytic Nitrene Transfer To Alkynes: A Novel and Versatile Route for the Synthesis of Sulfinamides and Isothiazoles
Rodríguez, Manuel R.; Beltrán Martín, Álvaro; Mudarra, Ángel L.; Álvarez, Eleuterio; Maseras, Feliu; Díaz Requejo, María Mar; Pérez Romero, Pedro José (Wiley, 2017)
A novel transformation is reported for the reaction of terminal or internal alkynes with the nitrene precursor PhI=NTs (Ts=p-toluenesulfonyl) in the presence of catalytic amounts of Tp(Br3)Cu(NCMe) (Tp(Br3)=hydrotris(3,4 ... -
Copper-Catalyzed N-F Bond Activation for Uniform Intramolecular C-H Amination Yielding Pyrrolidines and Piperidines
Bafaluy, Daniel; Muñoz Molina, José María; Funes Ardoiz, Ignacio; Herold, Sebastian; Aguirre, Adiran J. de; Zhang, Hongwei; Maseras, Feliu; Rodríguez Belderraín, Tomás; Pérez Romero, Pedro José; Muñiz, Kilian (Wiley, 2019-06)
The dual function of the N-F bond as an effective oxidant and subsequent nitrogen source in intramolecular aliphatic C-H functionalization reactions is explored. Copper catalysis is demonstrated to exercise full regio- and ... -
Functional-Group-Tolerant, Silver-Catalyzed N–N Bond Formation by Nitrene Transfer to Amines
Maestre Cera, Lourdes; Dorel, Ruth; Pablo, Óscar; Escofet, Imma; Sameera, W. M. C.; Álvarez, Eleuterio; Maseras, Feliu; Díaz Requejo, María Mar; Echavarren, Antonio M.; Pérez Romero, Pedro José (American Chemical Society, 2017)
Silver(I) promotes the highly chemoselective N-amidation of tertiary amines under catalytic conditions to form aminimides by nitrene transfer from PhI=NTs. Remarkably, this transformation proceeds in a selective manner ... -
Intermolecular Allene Functionalization by Silver-Nitrene Catalysis
Rodríguez, Manuel R.; Besora, María; Molina, Francisco; Maseras, Feliu; Díaz Requejo, María Mar; Pérez Romero, Pedro José (American Chemical Society, 2020-06)
Under silver catalysis conditions, using [Tp*,BrAg]2 as the catalyst precursor, allenes react with PhI═NTs in the first example of efficient metal-mediated intermolecular nitrene transfer to such substrates. The nature of ... -
Introducing the Catalytic Amination of Silanes via Nitrene Insertion
Rodríguez, Anabel. M; Pérez Ruíz, Jorge; Molina, Francisco; Poveda, Ana; Pérez Soto, Raúl; Maseras, Feliu; Díaz Requejo, María Mar; Pérez Romero, Pedro José (American Chemical Society, 2022-06-01)
The direct functionalization of Si−H bonds by the nitrene insertion methodology is described. A copper(I) complex bearing a trispyrazolylborate ligand catalyzes the transfer of a nitrene group from PhINTs to the Si−H bond ... -
Mechanism of Side Reactions in Alkane C-H Bond Functionalization by Diazo Compounds Catalyzed by Ag and Cu Homoscorpionate Complexes—A DFT Study
Braga, Ataualpa A. C.; Caballero Bevia, Ana; Urbano Baena, Juan; Díaz Requejo, María Mar; Pérez Romero, Pedro José; Maseras, Feliu (Wiley-VCH Verlag, 2011)
DFT computational methods were applied to the mechanistic study of the formation of fumarate and maleate derivatives in a solution containing alkane, TpBr3M [M=Cu, Ag; TpBr3=hydrotris(3,4,5-tribromopyrazolyl)borate] and ... -
Mechanistic and Computational Studies of the Atom Transfer Radical Addition of CCl4 to Styrene Catalyzed by Copper Homoscorpionate Complexes
Muñoz Molina, José María; Saamera, W. M. C.; Maseras, Feliu; Belderrain, Tomás R.; Pérez Romero, Pedro José (2011-02)
Experimental as well as theoretical studies have been carried out with the aim of elucidating the mechanism of the Atom Transfer Radical Addition (ATRA) of styrene and carbon tetrachloride with a TpxCu(NCMe) complex as the ... -
Mechanistic Studies on Gold-Catalyzed Direct Arene C–H Bond Functionalization by Carbene Insertion: The Coinage-Metal Effect
Romero Fructos-Vázquez, Manuel; Besora, María; Braga, Ataualpa A. C.; Díaz Requejo, María Mar; Maseras, Feliu; Pérez Romero, Pedro José (American Chemical Society, 2017)
The catalytic functionalization of the Csp 2-H bond of benzene by means of the insertion of the CHCO2Et group from ethyl diazoacetate (N2=CHCO2Et) has been studied with the series of coinage metal complexes IPrMCl (IPr ... -

Muñoz Molina, José María; Bafaluy, Daniel; Funes Ardoiz, Ignacio; Aguirre, Adiran J. de; Maseras, Feliu; Rodríguez Belderraín, Tomás; Pérez Romero, Pedro José; Muñiz, Kilian (American Chemical Society, 2022)
We have recently developed a method for the synthesis of pyrrolidines and piperidines via intramolecular C–H amination of N-fluoride amides using [TpxCuL] complexes as precatalysts [Tpx = tris(pyrazolyl)borate ligand and ... -
Two Copper-Carbenes from One Diazo Compound
Álvarez, María; Besora, María; Molina, Francisco; Maseras, Feliu; Rodríguez Belderraín, Tomás; Pérez Romero, Pedro José (American Chemical Society, 2021-03)
Many transition-metal complexes MLn decompose diazo compounds N2-CR1R2 generating metal-carbenes LnM-CR1R2 which transfer the carbene group to other substrates, constituting an important tool in organic synthesis. All ...
