Abstract

Comparative study on the proton and carbon NMR spectra for a series of N-and O-acyl substituted monohydroxypyridines (C5H4NOR: R=-H,-CHO,-COCH3,-COC (CH3) 3,- COCF3,-COC6H5,-SO2CH3,-SO2C6H4CH3 is reported. p] Characteristic 1H, 13 NMR and IR spectral features allow simple and unambiguous distinction between the isomeric N- and/or O-acyl-derivatives of 2-, 3-and 4-hydroxypyridines, so that both forms can clearly ...
