Chemistry is traditionally divided into organic and inorganic chemistry. COA of Formula: C4H6N2O, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 1072-67-9
Heterocyclic 5-amino uracil derivatives were prepared by catalytic amination of 1,3-dibenzyl-5-iodouracil using (CuOTf)2·PhH, 1,10-phenanthroline, dibenzylidene acetone, and Cs2CO3 as base in xylenes at 95C. Imidazole and 2-amino thiazoline were problematic using the Cu catalyst, but were effectively coupled using Ni(COD)2, dppf, and NatOBu in toluene at 100C. These are the first examples of catalytic amination with a uracil substrate.
