چکیده
The reaction of P-diketones 1 with phenyl hydrazine afforded 5-aryl-3-(1-
methyl-5-nitro-2-imidazoly1)-1-phenylpyrazole (2) and 3-aryl-5-(1-methyl-5-
nitro-2-imidazoly1) -1-phenylpyrazole (3). The reaction of diketones (1) with
urea in the presence of p-toluenesulfonic acid gave 4-(or 6-)aryl-6-(or 4-)(1-methyl-
5-nitro-2-imidazolyl)-1-(lH)pyrimidones (4). The structures of all
compounds were confirmed by spectroscopic methods
