EFFECT OF DELOCALIZATION OF ?-ELECTRON DENSITY ON THE BASICITY OF MONO- AND POLYCYCLIC KETONES, FROM THE DATA OF 17O NMR SPECTROSCOPY
By means of 17O NMR spectroscopy a large series of mono- and polycyclic aromatic ketones was studied in DMSO medium.A linear correlation between chemical shifts of the carbonyl group in 13C and 17O NMR spectra was found.We have established that the 17O chemical shift in ketones in their ordinary state reflects a tendency for reduction in basicity with decrease of the electronic density at the oxygen atom.It is shown that the basicity of aromatic ketones is affected by the degree of delocalization of ?-electron density both in the neutral and in the protonated form, and also by steric effects.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about538-58-9.Related Products of 538-58-9
