Abstract
Abstract The reaction of phenols with fluoro-2,4-dinitrobenzene, clean and quick when catalyzed by triethylamine in dimethylformamide, is shown to be ideal for the characterization of phenols. The resulting 2,4-dinitrophenyl ethers crystallize well and can be used in spectrophotometric and colorimetric quantitative analyses as well as for other purposes. Thirty new derivatives are described, and a list has been compiled of nearly 200 aryl 2,4-dinitrophenyl ethers scattered in the literature.
