An efficient method for visible-light-initiated, nickel-catalyzed Sonogashira C(sp)-C(sp2) coupling has been developed via an energy-transfer mode. Thioxanthen-9-one as a photosensitizer could significantly accelerate the arylation of alkynes with a wide range of (hetero)aryl halides in high yields. The cross-coupling reaction undergoes the stepwise oxidative addition of an arylhalide to nickel(0), transmetalation of the resulting aryl-Ni(II) halide species with Zn(II) acetylide into aryl-Ni(II) acetylide species, energy transfer from the excited state of thioxanthen-9-one to aryl-Ni(II) acetylide, and reductive elimination to the aryl alkyne. The experimental process involved the reaction of 4-Ethynylpyridine(cas: 2510-22-7SDS of cas: 2510-22-7)
4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. SDS of cas: 2510-22-7
