Aminoquinolate diarylboron complexes were prepared and utilized as photocatalysts in dual Ni/photoredox catalyzed carbon-oxygen construction reactions. Via this unified metallaphotoredox platform, diverse aryl halides could be conveniently coupled with acids, water and alcs. to afford aryl esters R1C(O)OR2 [R1 = H, 2-MeC6H4, 4-ClC6H4, etc.; R2 = 4-CNC6H4], phenols R3OH [R3 = Ph, 4-CO2EtPh, 4-BrC6H4, etc.], aryl ethers R4OR5 [R4 = 4-CNC6H4, 4-C(O)MeC6H4, 4-C(O)EtC6H4, etc.; R5 = Me, Et] resp. This method featured operational simplicity, broad substrate scope and good compatibility with functional groups. In the experiment, the researchers used many compounds, for example, 4-Methoxy-2-methylpyridine (cas: 24103-75-1COA of Formula: C7H9NO).
4-Methoxy-2-methylpyridine (cas: 24103-75-1) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.COA of Formula: C7H9NO
