Oxazolone (1) couples with aromaticdiazoniumsalts to yield the arylhydrazones (3a-c). Compound 3 reacts with aniline to give aryl hydrazone (5). Compound 5 was also obtained via converting 1 into the imidazolone (4) and subsequent treatment of 4 with aromaticdiazoniumsalts. Compounds 1 and 12 reacted with arylidenemalononitrile (6) to yield compounds 8 and 14 respectively. Also compounds 1, 12
