In 2011,Angewandte Chemie, International Edition included an article by Zhang, Min; Imm, Sebastian; Baehn, Sebastian; Neumann, Helfried; Beller, Matthias. Recommanded Product: 2-Hydroxy-N-phenylacetamide. The article was titled 《Synthesis of α-amino acid amides: ruthenium-catalyzed amination of α-hydroxy amides》. The information in the text is summarized as follows:
An efficient ruthenium-catalyzed amination of α-hydroxy acid derivatives is reported. Using a variety of amines, including anilines, primary and secondary aliphatic amines, and ammonia, a wide range of amino acid amides was obtained from α-hydroxy amides or esters. Combination of Ru3(CO)12 and 1,2-bis(dicyclohexylphosphino)ethane was the best catalyst system. In the experiment, the researchers used many compounds, for example, 2-Hydroxy-N-phenylacetamide(cas: 4746-61-6Recommanded Product: 2-Hydroxy-N-phenylacetamide)
2-Hydroxy-N-phenylacetamide(cas: 4746-61-6) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors.Recommanded Product: 2-Hydroxy-N-phenylacetamide In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well.
