    • Photoreduction of oxoisoaporphine dyes by amines: Transient-absorption and semiempirical quantum-chemical studies 
      Fuente, J. de la; Neira Pacheco, Verónica Alejandra; Saitz Barría, Claudio; Jullian Matthaei, Carolina; Sobarzo Sánchez, Eduardo (AMER CHEMICAL SOC, 2005-07-07)
      Photoreduction by amines of oxoisoaporphine dyes occurs via a stepwise mechanism of electron-proton electron transfer that leads to the metastable N-hydrogen oxoisoaporphine anion. During photoreduction that occurs from ...
    • Photoreduction of oxoisoaporphines. Another example of a formal hydride-transfer mechanism 
      Fuente, J. de la; Jullian Matthaei, Carolina; Saitz Barría, Claudio; Sobarzo Sánchez, Eduardo; Neira Pacheco, Verónica Alejandra; González, C.; López, R.; Pessoa Mahana, Hernán (ROYAL SOC CHEMISTRY, 2004)
      Photoreduction of 5,6-dimethoxy-, 5-methoxy- and 2,3-dihydro-7H-dibenzo[de, h] quinolin-7-one (A) by tertiary amines in oxygen-free solutions generates long-lived semi-reduced metastable photoproducts, A - NH-, via a ...
    • Unexpected formation of 1-diethylaminobutadiene in photosensitized oxidation of triethylamine induced by ... 
      Fuente, J. de la; Jullian Matthaei, Carolina; Saitz Barría, Claudio; Neira Pacheco, Verónica Alejandra; Poblete, Oscar.; Sobarzo Sánchez, Eduardo (AMER CHEMICAL SOC, 2005-10-28)
      Photoreduction of oxoisoaporphine dyes occurs via a stepwise mechanism of electron-protonelectron transfer that leads to the N-hydrogen oxoisoaporphine anion. When triethylamine, TEA, was used as the electron donor in ...
