Adonin, N. Yu.; Starichenko, V. F. published an article on January 31 ,2000. The article was titled 《Regioselective ortho-hydrodefluorination of pentafluorobenzoic acid by low-valent nickel complexes》, and you may find the article in Journal of Fluorine Chemistry.Quality Control of Ethyl 2,3,4,5,6-pentafluorobenzoate The information in the text is summarized as follows:
2,3,4,5-Tetrafluorobenzoic and 3,4,5-trifluorobenzoic acids were prepared in high yields by reaction of C6F5COOH with zinc in the presence of NiCl2-2′-bipyridine (or 1,10-phenanthroline) complexes. In the experimental materials used by the author, we found Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4Quality Control of Ethyl 2,3,4,5,6-pentafluorobenzoate)
Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4) belongs to esters. Esters are more polar than ethers but less polar than alcohols. Quality Control of Ethyl 2,3,4,5,6-pentafluorobenzoate They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.
