Comparison of the reactivities of dicarbonylbis(triphenylphosphine)cobaltate(1-), -iridate(1-), and -rhodate(1-) towards fluoroaromatic compounds》 were Booth, Brian L.; Haszeldine, Robert N.; Perkins, Ian. And the article was published in Journal of the Chemical Society, Dalton Transactions: Inorganic Chemistry (1972-1999) in 1975. Safety of Ethyl 2,3,4,5,6-pentafluorobenzoate The author mentioned the following in the article:
Nucleophilic substitution reactions of [M(CO)2(PPh3)2]- (M = Co, Ir) with perfluoroarom. compounds, e.g. pentafluoropyridine (C5F5N), gave aromatic metal complexes, e.g. 4-RC5F4N [R = M(CO)2(PPh3)2]. The relative reactivities of the Co, Ir, and corresponding Rh anions towards C5F5N were established by kinetic studies in the order [Rh(CO)2(PPh3)2]- > [Ir(CO)2(PPh3)2]- > [Co(CO)2(PPh3)2]-.Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4Safety of Ethyl 2,3,4,5,6-pentafluorobenzoate) was used in this study.
Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. They perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market.Safety of Ethyl 2,3,4,5,6-pentafluorobenzoate
