Preparation of unsymmetrically 2, 2'-disubstituted stilbenes

The new unsymmetrically 2, 2'-disubstituted stilbenes with NO2, F, Cl, Br, OCH3, CH3 and NH2 groups as substituents have been prepared Wittig or Perkin reactions. The compounds 1-8 were prepared due to the studies of fragmentation on electron impact, photochemistry and photoelectron spectroscopy. Their geometrical configuration has been established by 1H NMR and IR spectra.
