A ^(15)N NMR study of some azoles

Abstract

^(15)N NMR data are reported for 42 azoles, taken mostly at a standard concentration and in a common solvent (0.5 M dimethyl sulfoxide with a 0.01 M increment of Cr(acac)_3 for each nitrogen atom present). Signal assignments were assisted by comparison with ^(14)N line widths, the use of ^2J(^(15)N^1H) couplings, and shielding calculations obtained by the INDO/S–SOS approach. The generally large differences in nitrogen-shielding changes permitted rather facile shift assignments.
