A series of phenylallyl-substituted unsymmetrical ureas were synthesized in a one-pot procedure by reactions of cinnamoyl isocyanate, which was prepared from cinnamoyl azide by Curtius rearrangement, with various aromatic amines, 2-amino-5-aryl-1,3,4-thia

The rate of title reaction was studied in seven different solvents.The rate decreases in the order: glacial acetic acid = 80percent ethyl alcohol > ethyl alcohol methyl alcohol > acetone > aniline > benzene.The rate of pyrolysis reaction at the same temperature was very small if compared with that in any solvent.Linear relation was observed between k and (D-1/2D+1) also the (C-T) band (energy of charge transfer band) was shown to be linear in log k. ΔG(excit.) was found to be independent on solvent.The activation parameters of the reaction were determined.
