An efficient O-arylation of phenols and aliphatic alcs. with aryl halides was developed that uses an air-stable copper(I) complex, I, as the catalyst. This arylation reaction can be performed in good yield in the absence of Cs2CO3. A variety of functional groups are compatible with these reaction conditions with low catalyst loading levels. In the experiment, the researchers used many compounds, for example, 2-Phenoxypyridine (cas: 4783-68-0Synthetic Route of C11H9NO).
2-Phenoxypyridine (cas: 4783-68-0) 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). Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Synthetic Route of C11H9NO
