Abstract
(Z)-2-(4-Halogenophenyl)-3-(thiophen-3-yl)acrylonitrile can be prepared by condensation of thiophene-3-carbaldehyde with arylacetonitrile halides in the presence of catalytic amounts of NaOCH3 at room temperature. Secondary arylamines reacted with (Z)-2-(4-halogenophenyl)-3-(thiophen-3-yl)acrylonitriles to afford thiophenylacrylonitrile derivatives containing a triphenylamine moiety on catalysis by Pd(OAc)2/P(o-tolyl)3 at 120°C in toluene. The UV-Vis absorption and photoluminescent (PL) spectra of the products in CH2Cl2were investigated.
