Chemistry is traditionally divided into organic and inorganic chemistry. HPLC of Formula: C8H5ClO2, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 54109-03-4
A simple and efficient method for the coupling of aryl iodides with heterocyclic compounds such as diazoles that does not require the use of alkoxide bases is described. The C-N bond forming procedure shows that the combination of air stable CuI and 1,10-phenanthroline in the presence of KF/Al2O3 comprises an extremely efficient and general catalyst system for the N-arylation of aryl iodides. Different functionalized aryl iodides were coupled with diazoles using this method. Georg Thieme Verlag Stuttgart.
