O-alkylated vanillin derivatives 2a–f and acetylferrocene react under Claisen–Schmidt conditions, resulting in good-to-high yields of the corresponding ferrocene chalcones 3a–f. None of the resultant compounds 3b–f has been previously described in the literature. All synthesized compounds were characterized by spectral and physical data, whereas two of them, 1-ferrocenyl-3-(4-ethoxy-3-methoxyphenyl)-prop-2-en-1-one...
