Heterocycles | 1978

15)N Nuclear Magnetic Resonance Spectroscopy of Some Nitrogen Heterocycles

Kenneth L. Williamson; John D. Roberts

The potential power and utility of ^(15)N NMR spectroscopy in heterocyclic chemistry is illustrated by the natural-abundance high-resolution ^(15)N NMR spectra of representative thiadiazoles and related compounds. The ^(15)N chemical shifts in these compounds were found to range over 250 ppm. The advantages and limitations of the method are discussed.
