| dc.description.abstract | New Schiff base (Z)-1-((5-bromothiophen-2-yl)methylene)-2-(2,4dinitrophenyl)hydrazine was made available through condensing of (2,4dinitrophenyl)hydrazine with 5-bromothiophene-2-carbaldehyde in good yield and fast technique, as seen in Scheme 1. Based on the theoretical calculation and experimental physical measurements Z- isomer is favored over E- isomer due to the intera H-bond between N-H…S, to form more stable six-membered ring. The desired product formation was monitored by FT-IR and UV-visible, the structure was suggested based on: elemental analysis, EI-Ms, UV-visible, FTIR spectral, TG/DTG. 1H-NMR and DFT-computational analysis. | en_US |
