摘要

~13C chemical shifts for 23 mono-and di-substituted phenyl styryl ketones have been determined. The shieldings and deshieldings are compared with previous results for other aromatic derivatives. Correlations of the ~13C chemical shifts of vinyl carbons with Hammett sigma parameters has been determined to provide a consistent picture of electronic effects transmitted through the carbon framework of the compounds studied. Slopes obtained from such Hammett's plots are termed as rho, and using these 'rho' values applicability of interactive free energy relationship to chemical shift values has been tested. The cross-interaction constants q_x and q_y values for C-alpha are found to be -1.02 and for C-beta are - 1.46 and -1.19.
