Nickel-catalyzed aryl amination and etherification were driven with sunlight using a surface-modified carbon nitride to extend the absorption of the photocatalyst into a wide range of the visible region. In contrast to traditional homogeneous photochem. methodologies, the lower cost and higher recyclability of the metal-free photocatalyst, along with the use of readily available sunlight, provide an efficient and sustainable approach to promote nickel-catalyzed cross-couplings. In the experiment, the researchers used many compounds, for example, 4-Methoxy-2-methylpyridine (cas: 24103-75-1Quality Control of 4-Methoxy-2-methylpyridine).
4-Methoxy-2-methylpyridine (cas: 24103-75-1) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·molâ? in pyridine vs. 150 kJ·molâ? in benzene). Reduced pyridines, namely tetrahydropyridines, dihydropyridines and piperidines, are found in numerous natural and synthetic compounds. The synthesis and reactivity of these compounds have often been driven by the fact many of these compounds have interesting and unique pharmacological properties.
