Abstract: cf. CA 63, 7041d. By the aldol condensation of the acetylferrocenes or 1-acetyl-1'-benzoylferrocenes with aromatic aldehydes, ferrocene analogs of chalcones were prepd. and detd. by thin-layer chromatography and polarography. In the chalcones derived from the acetylferrocenes the halfwave potentials were plotted in the diagram against Hammett's σ const. A linear relationship was detd. as expressed in the equation: ΔΕ⁰_1/2 = + 0.17 σ. In the chalcones derived from the 1-acetyl-1'-benzoylferrocenes, the values of halfwave potentials practically do not depend on the nature of the substituent. Analyses of 22 prepd. compds. are given.
