Assignments of NMR Spectral Data of a Novel Carbazole-Triazinoindole Based N-Acylhydrazone Derivative

doi:10.11938/cjmr20202803

Abstract

Abstract: N-acylhydrazone compounds have two isomers, E/cis and E/trans, in polar solvents. In this work, ¹H and ¹³C nuclear magnetic resonance (NMR) signals, coupling constants (J), and the spatial structures of the two isomers (E/cis and E/trans) of a novel carbazole-triazinoindole based N-acylhydrazone derivative 3, 2-(5H-[1,2,4] triazine[5,6-b]indol-3-ylthio)-N'-(9-ethylcarbazol-3-ylmethylene)acetylhydrazine, were obtained by one-dimensional and two-dimensional NMR techniques, infrared spectroscopy (IR) and elemental analysis. The ratios of the two isomers were determined.

Key words: nuclear magnetic resonance (NMR), assignment, 2D NMR, carbazole-triazinoindole, N-acylhydrazone derivative
