Rozatian, Neshat published the artcileA quantitative reactivity scale for electrophilic fluorinating reagents, Related Products of pyridine-derivatives, the publication is Chemical Science (2018), 9(46), 8692-8702, database is CAplus and MEDLINE.
The N-F reagent was currently determined through empirical experimentation in the absence of quant. values for electrophilicities. An exptl.-determined kinetic reactivity scale for ten N-F fluorinating reagents, including Selectfluor, NFSI, Synfluor and several N-fluoropyridinium salts, in CH3CN ws reported. The reactivity scale, which covers eight orders of magnitude, employs para-substituted 1,3-diaryl-1,3-dicarbonyl derivatives to measure relative and absolute rate constants The para-substituted 1,3-diaryl-1,3-dicarbonyl scaffold delivers a convenient, sensitive spectrophotometric reporter of reactivity that also led to the discovery of a unique form of tautomeric polymorphism.
Chemical Science published new progress about 107263-95-6. 107263-95-6 belongs to pyridine-derivatives, auxiliary class Fluorination reagent, name is 1-Fluoropyridiniumtriflate, and the molecular formula is C6H5F4NO3S, Related Products of pyridine-derivatives.
