1-(2,4-Dinitrophenyl)-2-((<i>Z</i>)-2-((<i>E</i>)-4-fluorobenzylidene)-3,4-dihydronaphthalen-1(2<i>H</i>)-ylidene)hydrazine

Abstract

The reaction of (E)-2-(4-fluorobenzylidene)-3,4-dihydronaphthalen-1(2H)-one and (2,4-dinitrophenyl)hydrazine in boiling ethanol containing hydrochloric acid (0.2 mL; 37%) for 1.5 h gave 1-(2,4-dinitrophenyl)-2-(2-(4-fluorobenzylidene)-3,4-dihydronaphthalen-1(2H)-ylidene)hydrazine in a 90% yield. Various spectral analyses, including NMR, and X-ray crystallography established the structure of the newly synthesized hydrazone.
