Abstract

The (13) C NMR resonances of 19 1-acyl-3-(2-nitro-5-substitutedphenyl)-4,5-dihydro-1H-pyrazoles, and 19 1-acyl-3-(2-amino-5-substituted)-4,5-dihydro-1H-pyrazoles, were completely assigned using the concerted application of one- and two-dimensional NMR experiments (DEPT, gs-HSQC and gs-HMBC).
