Structural characterization of a new chalcone compound containing a thiophene moiety: (E)-3-(5-Bromothiophen-2-YL)-1- (2,5-Dichlorothiophen-3-YL)-2-Propen-1-One
The crystal structure of the new chalcone derivative (E)-3-(5-bromothiophen-2-yl)-1-(2,5-dichlorothiophen- 3-yl)-2-propen-1-one is synthesized and structurally characterized by spectroscopic IR, NMR, and HRMS techniques. Its crystal and molecular structure is determined from the single crystal X-ray...
