Oxidative hydroxylation of arylboronic acids to the corresponding phenolic compounds R-OH [R = 2-MeC6H4, 2-naphthyl, 3-ClC6H4, etc.] under metal- and base-free aerobic conditions was successfully demonstrated using biopolymer support (chitosan or chitosan immobilized onto carbon nanotubes (CNT@Chitosan)). Hydrogen peroxide, as an eco-friendly oxidant, was compatible with the biopolymer supports and provided hydroxylation products in an efficient manner. The CNT@chitosan biopolymer support was particularly interesting for its potential recyclability. In the experiment, the researchers used many compounds, for example, 5-Hydroxy-2-methoxylpyridine (cas: 51834-97-0Recommanded Product: 51834-97-0).
5-Hydroxy-2-methoxylpyridine (cas: 51834-97-0) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Recommanded Product: 51834-97-0
