ORTEGA-ALFARO, María C.; LOPEZ-CORTES, José G.; TOSCANO, Rubén A.  and  ALVAREZ-TOLEDANO, Cecilio. Electronic Effects on the Reactivity of Cross-Conjugated Carbonyl Systems with Fe2(CO)9. J. Mex. Chem. Soc [online]. 2005, vol.49, n.2, pp.124-133. ISSN 1870-249X.

Neste trabalho foram estudados os efeitos eletrônicos induzidos por p-substituintes no anel fenilico de diversos compostos carbonílicos conjugados [4-/>-R-fenil-1-(1,3-ditiolano-2-ilideno)-3E-buteno-2-ona, onde R=NO2, Cl, Br, OMe, NEt2 (2-6)], e sua reatividade frente a Fe2(CO)9 usando o diagrama de Hammett. А estrutura dos compostos (3 e 4b) foi totalmente estabelecida poranálise de difração de raio-X.

Keywords : iron(0) complexes; C-S bond activation; reactivity; Hammett plot; X-ray diffraction.
