## Abstract Substituent effects on the ^13^C and ^1^H chemical shifts have been studied for derivatives of 3‐benzylidene‐2, 4‐pentanedione. A significant correlation has been found between chemical shifts of the __Z__ carbonyl group (C‐2) and Hammett constants, while no correlation has been found f
