DERIVATIVES OF AZIDOCINNAMIC ACID IN THE SYNTHESIS OF 2-AMINO-4-ARYLIDENE-1H-IMIDAZOL-5(4H)-ONES

Abstract
A method for the synthesis of 2-amino-4-arylidene-1H-imidazol-5(4H)-ones is proposed based on the reaction of various aromatic isocyanates with phosphazenes derived from azidocinnamic acid amides. The spectral-luminescent properties of the obtained compounds were studied. The products were shown to possess the (Z)-configuration with the help of two-dimensional spectroscopy.
