A protocol for the auxillary directed C-H chlorination of phenol derivatives using catalytic amounts of palladium acetate that is amenable to the late-stage chlorination of diflufenican and estrone was developed. The 2-pyridine group allows for a highly efficient palladium-catalyzed chlorination and sequential ortho C-H functionalization reaction of phenol derivatives to produce a variety of sym. and unsym. 2,4,6-trisubstituted phenols. In the experimental materials used by the author, we found 6-Phenoxynicotinonitrile(cas: 99902-72-4Recommanded Product: 6-Phenoxynicotinonitrile)
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.Recommanded Product: 6-Phenoxynicotinonitrile
