Final Thoughts on Chemistry for Tetrafluorophthalic anhydride

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 652-12-0, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 652-12-0, in my other articles.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, SDS of cas: 652-12-0, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 652-12-0, Name is Tetrafluorophthalic anhydride, molecular formula is C8F4O3

When acted upon by HF/SbF5 at 95 C, carbonyl groups of perfluorinated acetophenone (10), 3,4-dihydronaphthalen-1(2H)-one (8), 2,3-dihydronaphthalene-1,4-dione (9), benzocyclobutenone (6), benzocyclobutenedione (7) and indan-1-one (1) are converted into difluoromethylene groups to give the corresponding perfluoroaromatic products. Perfluoroindan-2-one (5), under the same conditions, is transformed to bis(perfluoroindan-2-yl) ether (21). On heating with HF/SbF5, perfluoroindan-1,3-dione (2) isomerizes into perfluoro-3-methylenephthalide (4) at 95 C, and gives 4,5,6,7-tetrafluoro-3-trifluoromethyl-phthalide (14) at 130 C. Compound 4 in the absence of a solvent dimerizes giving perfluorodispiro[phthalide-3,1?-cyclobutane-2?,3?-phthalide] (18), and when heated with SbF5 at 130 C, it is converted into perfluoro-3-methylphthalide (3). When acted upon by HF/SbF5 at 95 C, perfluorinated benzoic acid (12) and phthalic anhydride (13) give the corresponding products with trifluoromethyl groups.
