Substituent effects on the 13C and 1H 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 and (C-2) and Hammett constants, while no correlation has been found for the E carbonyl group (C-4).Attempts have been made to determine the structural factors which influence these effects.The conformation of 3-benzylidene-2,4-pentanediones has been determined by 13C and 1H NMR spectroscopy.
