Copper-Induced Ammonia N-H Functionalization
Álvarez, María; Álvarez, Eleuterio; Romero Fructos-Vázquez, Manuel; Urbano Baena, Juan; Pérez Romero, Pedro José (Royal Society of Chemistry, 2016)
The activation of ammonia has been achieved with the aid of the TpMsCu core (TpMs = hydrotris(3-mesityl-pyrazolyl)borate). Complexes of the general composition TpMsCu(amine) (1–4) including the ammonia adduct TpMsCu(NH3) ... -
Evidencing an inner-sphere mechanism for NHC-Au(I)- catalyzed carbene-transfer reactions from ethyl diazoacetate
Romero Fructos-Vázquez, Manuel; Urbano Baena, Juan; Díaz Requejo, María Mar; Pérez Romero, Pedro José (Beilstein-Institut, 2015)
Kinetic experiments based on the measurement of nitrogen evolution in the reaction of ethyl diazoacetate (N2CHCO2Et, EDA) and styrene or methanol catalyzed by the [IPrAu]+ core (IPr = 1,3-bis(diisopropylphenyl)imidazole ... -
Exclusive Aromatic vs Aliphatic C-H Bond Functionalization by Carbene Insertion with Gold-based Catalysts
Rivilla de la Cruz, Iván; Gómez Emeterio, Bella Pilar; Romero Fructos-Vázquez, Manuel; Díaz Requejo, María Mar; Pérez Romero, Pedro José (American Chemical Society, 2011)
The direct functionalization of aromatic C-H bonds by carbene insertion from diazocompounds catalyzed by gold complexes with N-heterocyclic ligands is described. The reaction is completely selective toward the Csp2-H bonds, ... -
