Chemistry is traditionally divided into organic and inorganic chemistry. Product Details of 3922-40-5. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 3922-40-5
A series of 1,10-phenanthroline derivatives were used as supporting ligands for copper-catalyzed Ullmann reaction in neat water. The catalytic system based on 4,7-dihydroxy-1,10-phenanthroline has demonstrated the promising catalytic performances for aryl bromides. The catalytic system was applicable to a wide scope of substrates, high catalytic activity and selectivity were observed for the reactions of electron-deficient, electron-rich, and heterocyclic aryl bromides with imidazoles containing different steric hindrance. The superior promoting effect of 4,7-dihydroxy-1,10-phenanthroline is attributed to its water solubility under the basic conditions. You can?t hold back the power of water: pH-Responsive 4,7-dihydroxy-1,10-phenanthroline exhibits an excellent promoting effect in copper-catalyzed Ullmann cross-coupling reaction of aryl bromides and imidazoles with different steric hindrance in neat water.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 3922-40-5, you can also check out more blogs about3922-40-5
