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.

The electronic effects induced by p-substituents on the phenyl ring of several novel cross-conjugated carbonyl compounds [4-p-R-phenyl-1-(1,3-dithiolane-2-ylidene)-3E-butene-2-one, where R= NO2, Cl, Br, OMe, NEt2 (2-6),] and their reactivity towards Fe2(CO)9 have been studied using a Hammett plot. The structure of two compounds (3 and 4b) was fully established by X-ray diffraction analysis.

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