Peculiarities of nmr 1h and 13c spectra of benzoates and benzoylformates carbalkoxyl fragments
peculiarities of NMR 1H and 13C spectra of benzoates and benzoylformates carbalkoxyl fragments have been studied. Characteristic values of chemical shifts of three types: carboxyl, a- and b-carbon atoms of alkoxyl groups have been presented in NMR 13C spectra. Characteristic values of protons attached to the mentioned atoms have been given in PMR spectra. Analogous parameters of some carbalkoxyl-containing compounds of general formula Y–COO–CH2–R have been presented for comparison.
