摘要: A critical overview of the recent literature data and our results on oxyfluorination C–H to C–F bond with metal fluorides is presented. Some important aspects that require further investigation, in order obtain a better understanding reaction mechanism develop general approach catalysts design are discussed. In particular, ethene, utilizing different fluorides, pulse continuous reactors, was studied. Obtained indicated presence mixed fluoroperovskite structure, such as AgCuF3, led improved reactant conversion higher selectivity vinyl fluoride, comparison single fluorides. CO2 formed from secondary parallel upon ethene oxidation, because oxides catalysts. The difficulties met regeneration Ag° during oxyfluorination, addressed search for new starting materials synthesis perovskite-like materials. Still, among prepared mixtures only case AgCuF3 formation evidenced by means XRD; behaviour explained Goldschmidt factor t.
