    Unexpected N-C bond fission of fused N-alkylbenzimidazolium salts. A new approach to pyrido[1,2-a]- or pyridazino[1,6-a]benzimidazoles

    Get PDF
    The reaction of N-carboxymethylpyrido[1,2-a]- and pyridazino[1,6-a]benzimidazolium salts with thionyl chloride resulted in an N-C bond fission, yielding the corresponding pyrido[1,2-a]- and pyridazino[1,6-a]benzimidazoles. A similar dealkylation process was observed when analogous N-propargylic derivatives were treated with Cu (II) acetate.Universidad de Alcal

    Publishing performance in economics: Spanish rankings (1990-1999).

    Get PDF
    This paper contributes to the growing literature that analyses the Spanish publishing performance in Economics throughout the 1990s. Several bibliometric indicators are used in order to provide Spanish rankings (of both institutions and individual authors) based on Econlit journals. Further, lists of the ten most influential authors and articles over that period, in terms of citations, are reported.Rankings; economics; Bibliometric indicators;
