Abstract
Diphenylallylidenes are the compounds of immense biological importance. The presentwork
starts with the synthesis of substituted chalcones and 2-amino-benzothiazoles. The chalcones were
synthesized from substituted benzaldehyde and acetophenone. 2-amino-benzothiazoles were synthesized
from substituted aniline with potassium thiocyanate. The reaction of substituted chalcones and 2
aminobenzothiazoles gives corresponding 1,3-diphenylallylidene derivative by using conc. sulfuric acid in
dimethylformamide solvent at reflux condition. All the newly synthesized compounds were characterized on
the basis of their physical, spectral and analytical data.
Keywords
