INVESTIGAREA METODELOR DE SINTEZĂ PENTRU 3-(ANTRACEN-9-IL)-1-(4-IZOTIOCIANATOFENIL)-PROP-2-EN-1-ONĂ

Abstract

Lucrarea prezintă o descriere succintă a izotiocianatochalconelor fluorescente şi redă unele metode de obţinere a lor. În aspect mai detaliat sunt cercetate metodele de obţinere a izotiocianatochalconelor ce conţin fragmentul antracenic. Rezultate bune atestă metoda ce include condensarea 3-(4-acetilfenil)-1,1-dimetiltioureei cu antracen-9-carbaldehidă, urmată de eliminarea dimetilaminei din chalconele corespunzătoare la tratare cu anhidridă acetică sau cu clorură de acetil.THE INVESTIGATION OF SYNTHESIS METHODS FOR 3-(ANTHRACEN-9-YL)-1-(4-ISOTHIOCYANATOPHENYL)PROP-2-EN-1-ONEThe paper presents a review of the isothiocyanatochalcones fluorescents and their methods of synthesis. Various methods were investigated for obtaining anthracene moiety containing isothiocyanatochalcones. Good results give the method which includes condensation of 3-(4-acetylphenyl)-1,1-dimethylamine with antracene-9-carbaldehyde flowed by elimination of dimethylamine in the treatment of corresponding chacones with acetyl anhydride or acetyl chloride.
