Abstract

The transmission of electronic effects across the ferrocene analogues of chalcones [3‐aryl‐1‐ferrocenyl‐2‐propene‐1‐ones (series 1) and 1‐aryl‐3‐ferrocenyl‐2‐propene‐1‐ones (series 2)], as well as the conformations of both types of ferrocene analogues have been studied. The ferrocene analogues of chalcones of series 1 were found to be in a non‐planar conformation. Their H‐α and C‐α chemical shifts are more sensitive to the resonance than to the inductive effects of substituents. The C‐α chemical shifts of the ferrocene analogues of chalcones of series 2 are more sensitive to the inductive than to the resonance effects of substituents. The transmission of the substituent effects to the ferrocene moiety is also briefly discussed.
