Aerobic Intramolecular Carbon-Hydrogen Bond Oxidation Promoted by Cu(I) Complexes
Álvarez, María; Molina, Francisco; Romero Fructos-Vázquez, Manuel
; Urbano Baena, Juan; Álvarez, Eleuterio; Sodupe, Mariona; Lledós, Agustí; Pérez Romero, Pedro José (Royal Society of Chemistry, 2020-09)
The oxidation of C–H bonds by copper centres in enzymes with molecular oxygen takes place in nature under ambient conditions. Herein we report a similar transformation in which under ambient pressure and temperature (1 ... -
Alkoxydiaminophosphine Ligands as Surrogates of NHCs in Copper Catalysis
Pizarro, Juan Diego; Molina, Francisco; Romero Fructos-Vázquez, Manuel; Pérez Romero, Pedro José (Wiley, 2020-08)
A family of phosphine ligands containing a five‐membered ring similar to the popular N‐heterocyclic carbene ligands and an alkoxy third substituent has been developed. These alkoxydiaminophosphine ligands (ADAP) can be ... -
Carbene-Controlled Regioselective Functionalization of Linear Alkanes under Silver Catalysis
Álvarez, María; Molina, Francisco; Pérez Romero, Pedro José (American Chemical Society, 2022)
Control of the regioselectivity in the functionalization of C–H bonds of linear alkanes C2H2n+2 via carbene transfer from diazo compounds is restricted to the use of rhodium-based catalysts, which govern the reaction outcome ... -
Copper‐Catalyzed Selective Pyrrole Functionalization by Carbene Transfer Reaction
Rodríguez, Anabel M.; Molina, Francisco; Díaz Requejo, María Mar; Pérez Romero, Pedro José (Wiley, 2020-02)
1H‐Pyrroles can be directly functionalized by means of the incorporation of carbene groups from diazo compounds, in a process catalyzed by TpxCu complexes (Tpx=hydrotrispyrazolylborate ligand). The reactions take place ... -
Gold Complexes with ADAP Ligands: Effect of Bulkiness in Catalytic Carbene Transfer Reactions (ADAP = Alkoxydiaminophosphine)
Pizarro, Juan Diego; Molina, Francisco; Romero Fructos-Vázquez, Manuel; Pérez Romero, Pedro José (American Chemical Society, 2020-07)
A family of gold(I) complexes of composition AuCl(ADAP) (ADAP = alkoxydiaminophosphine) has been synthetized through a one-pot simple protocol in which the ADAP ligand is prepared in situ before reaction with the ... -
Heterogeneous Olefin Aziridination Reactions Catalyzed by Polymer-Bound Tris(triazolyl)methane Copper Complexes
Ramírez Rodríguez, Manuel; Molina, Francisco; Etayo, Pablo; Pericàs, Miquel A.; Pérez Romero, Pedro José; Díaz Requejo, María Mar (Wiley, 2021)
Efficient olefin aziridination has been achieved with a tris(triazolyl)methane copper catalyst supported onto polystyrene. Aryl, alkyl and methoxycarbonyl-substituted olefins are converted into N-tosylaziridines in good ... -
Important Role of NH-Carbazole in Aryl Amination Reactions Catalyzed by 2‑Aminobiphenyl Palladacycles
Rama, Raquel J.; Maya, Celia; Molina, Francisco; Nova, Ainara; Nicasio Jaramillo, María Carmen (American Chemical Society (ACS), 2023-03)
2-Aminobiphenyl palladacycles are among the most successful precatalysts for Pd-catalyzed cross-coupling reactions, including aryl amination. However, the role of NH-carbazole, a byproduct of precatalyst activation, remains ... -
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 ... -
Stable N-heterocyclic carbene (NHC)-palladium(0) complexes as active catalysts for olefin cyclopropanation reactions with ethyl diazoacetate
Martín, Carmen; Molina, Francisco; Álvarez, Eleuterio; Rodríguez Belderraín, Tomás (Wiley-VCH Verlag, 2011)
The Pd(0) complexes NHCPdLn (NHC = N-heterocyclic carbene ligand; L = styrene for n = 2 or PR3 for n = 1) efficiently catalyze the olefin cyclopropanation using ethyl diazoacetate (EDA) as the carbene source with ... -
The first heavy-metal hot subdwarf composite binary SB 744
(EDP Sciences, 2021)Aims. A radial velocity follow-up of the long-period sdOB+G1V type spectroscopic binary SB 744 revealed strong lines of fluorine and lead in the optical spectrum of the sdOB star and subsolar metallicity in the G1V ... -
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 ...
