Unsym. di(heteroaryl) ethers were synthesized by the rhodium-catalyzed heteroaryl exchange reaction of heteroaryl aryl ethers and heteroaryl esters at equilibrium [e.g., 2-phenoxybenzothiazole + 3-pyridyl benzoate → 2-(3-pyridyloxy)benzothiazole + Ph benzoate]. Diverse unsym. di(heteroaryl) ethers containing five- and six-membered heteroarenes were obtained. Di(heteroaryl) ethers can be synthesized starting from diaryl ethers, because heteroaryl aryl ethers are obtained by the heteroaryl exchange reaction of diaryl ethers. In the experiment, the researchers used many compounds, for example, 6-Phenoxynicotinonitrile(cas: 99902-72-4SDS of cas: 99902-72-4)
6-Phenoxynicotinonitrile(cas: 99902-72-4) belongs to nitriles. Nitriles are found in many useful compounds. Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons.SDS of cas: 99902-72-4
