    • Aerosoles atmosféricos de naturaleza inorgánica, contaminación en Santiago de Chile 
      Préndez Bolívar, María Margarita; Ortíz, Jorge; Zolezzi Carvallo, Santiago; Campos, Cecilia; Apablaza, Nibaldo (Sociedad Chilena de Enfermedades Respiratorias, 1991)
      Se da una visión suscinta de las características fisocoquímicas de los aerosoles atmosféricos en general, enfatizándose las correspondientes a los aerosoles urbanos y su impacto sobre la salud humana y el medio ambiente. ...
    • Composición elemental de aerosoles sub-antárticos en función del tamaño de partícula. 
      Préndez Bolívar, María Margarita; Zolezzi Carvallo, Santiago (Instituto Antártico Chileno, 1982)
      La especial situación geográfica de la Antártica y sus características meteorológicas hacen que el estudio de sus aerosoles atmosféricos sea particularmente interesante. En este trabajo se ha estudiado la composición ...
    • Cu(H(2)btec)(bipy)](infinity): a novel metal organic framework (MOF) as heterogeneous catalyst for the ... 
      Brown, Kareen; Zolezzi Carvallo, Santiago; Aguirre, Pedro; Venegas Yazigi, Diego; Paredes García, Verónica; Baggio, Ricardo; Novak, Miguel; Spodine Spiridonova, Evgenia (Royal Society of Chemistry, 2009)
      A new extended metal-organic framework [Cu(H(2)btec)(bipy)](infinity) (1) (H(4)btec=1,2,4,5-benzenetetracarboxylic acid; bipy= 2,2'-bipyridine) has been hydrothermally synthesized. Violet crystals are formed in a monoclinic ...
    • Epoxidation of styrene with iodosylbenzene in the presence of copper(II) Schiff-base complexes 
      Zolezzi Carvallo, Santiago; Spodine Spiridonova, Evgenia; Decinti, Antonio (Elsevier Ltd, 2003)
      Copper(II) complexes with salen Schiff-base ligands derived from ethylenediamine or (S,S)-1,2-diphenylethylenediamine and salicylaldehyde or 5-methoxy, 5-bromo and 5-nitrosalicylaldehyde have been tested as catalysts for ...
    • EVOLUTION OF LEAD CONCENTRATION IN THE PARTICULATE MATTER OF SANTIAGO, CHILE, SINCE 1978 
      Préndez Bolívar, María Margarita; Ortíz, Jorge; Zolezzi Carvallo, Santiago (KLUWER ACADEMIC PUBL, 1993-01)
      Santiago is a city of over 4.5 million inhabitants and about 415000 motor vehicles using leaded gasoline. Twenty-four-hour samples were taken of total and fractionated particulate matter using a low-volume system and two ...
    • Hidrogenación de acetofenona catalizada por complejos de hierro (II) con ligandos fósforo nitrógeno 
      Cariaga Morales, Paulo Alejandro (Universidad de Chile, 2017)
      Este trabajo de tesis tenía por objeto sintetizar y caracterizar complejos de hierro (II) con ligandos fosforo nitrógeno, los cuales fueron ensayados como catalizadores homogéneos en la reacción de hidrogenación de ...
    • Methoxycarbonylation of olefins catalyzed by palladium(II) complexes containing naphthyl(diphenyl)phosphine ligands 
      Zolezzi Carvallo, Santiago; Moya, Sergio A.; Valdebenito, Gonzalo; Abarca, Gabriel; Parada Aliste, José; Aguirre, Pedro (John Wiley and Sons Ltd, 2014)
      Palladium(II) complexes containing phosphine donor ligands derived from naphthyl(diphenyl)phosphine were synthesized and characterized by NMR and elemental analysis. The complexes were studied as catalyst precursors in the ...
    • The stereoselective synthesis of the Werner complex with substoichiometric sugars 
      Parada Aliste, José; Larrazábal Rojas, Guillermo; Aguirre Álvarez, Pedro; Zolezzi Carvallo, Santiago; Vega, Carmen; Garrido, Cristián (Sociedad Chilena de Química, 2008)
      A tetranuclear complex of Co(III) with hydroxo bridges, so-called “Werner Complex”, was synthesized in the presence of several sugars (1-8) with partial resolution of this complex. The sugars in 10 mol % with respect to ...
