tailieunhanh - Spectral characterization of some hydrazones derived from isoeugenoxyacetic acid

Eight hydrazones were synthesized from isoeugenoxyacetic acid via a three-step procedure (esterification, conversion to hydrazide, condensation with aromatic aldehydes and p-methylacetophenone). The IR, 1H NMR and 13C NMR spectra of the hydrazones were analyzed. 1H NMR and 13C NMR signals were assigned on the basis of spin-spin splitting patterns and cross peaks on HSQC, HMBC spectra. |
