Gazitua, Marcela; Tapia, Ricardo A.; Contreras Ramos, Renato; Campodonico, Paola R. (Royal Society of Chemistry, 2018)The reaction of 2,4-dinitrobenzenesulfonyl chloride toward propylamine was kinetically evaluated in 19 organic solvents and 10 ionic liquids as reaction media. This study was compared with a previous study to experimentally ...

Alarcón Esposito, Jazmín; Contreras Ramos, Renato; Tapia, Ricardo A.; Campodónico, Paola R. (2016)We report an experimental study on the effect of solvents on the model SNAr reaction between 1-chloro-2,4dinitrobenzene and morpholine in a series of pure ionic liquids (IL). A significant catalytic effect is observed with ...

Lagos, Carlos F.; Araya Secchi, Raúl; Thomas, Pablo; Pérez-Acle, Tomás; Tapia, Ricardo A.; Salas, Cristian O. (2012)Trypanosoma cruzi glutamate cysteine ligase (TcGCL) is considered a potential drug target to develop novel antichagasic drugs. We have used a variety of computational methods to investigate the interactions between TcGCL ...

Urzua, Julio I.; Contreras Ramos, Renato; Salas, Cristian O.; Tapia, Ricardo A. (2016)A new and efficient synthesis of 2-arylbenzoxazoles and benzothiazoles using a copper N-heterocyclic carbene complex is described. In a simple protocol a variety of 2-substituted benzoxazoles and benzothiazoles were obtained ...

Ormazábal Toledo, Rodrigo; Contreras Ramos, Renato; Tapia, Ricardo A.; Campodónico, Paola R. (2013)We herein report results obtained from an integrated experimental and theoretical study on aromatic nucleophilic substitution (SNAr) reactions of a series of amines towards 1-fluoro-2,4-dinitrobenzene in water. Specific ...

Briones O., Ximena; Tapia, Ricardo A.; Campodonico, Paola R.; Urzúa Acevedo, Marcela; Leiva, Angel; Contreras Ramos, Renato; González Navarrete, Javier (Elsevier, 2018)The main motivation of this work is to obtain poly (ionic liquids) (PILs) derived from poly (4-vinyl pyridine) of different hydrophobic character containing BF4-, PF6-, (CF3SO2)(2) N- and CF3SO3- as counterions. PILs were ...
