Usage

General Description

Bromodifluoroacetyl fluoride is a chemical compound with the formula C2BrF2O2. It is a colorless, highly reactive, and toxic liquid with a pungent odor. It is primarily used as a reagent in organic synthesis, especially in the production of pharmaceuticals and agrochemicals. Bromodifluoroacetyl fluoride is a strong fluorinating agent and can react violently with water, alcohols, and amines. It is also a potential occupational hazard, as exposure to this compound can cause skin and eye irritation, as well as respiratory and neurological effects. Due to its hazardous properties, proper handling and storage of bromodifluoroacetyl fluoride are crucial to ensure safety in its use.

Formation of bromodifluoroacetyl fluoride, CF2BrC(O)F, in the thermal gas-phase oxidation of bromotrifluoroethene, CF2CFBr, initiated by trifluoromethylhypofluorite, CF3OF

The oxidation of CF2CFBr by molecular O2, initiated by CF3OF, has been studied at 273, 253.5, 239 and 218 K. The initial pressure of CF3OF was varied between 0.9 and 2.4 Torr, that of CF2CFBr between 11.5 and 30.7 Torr and that of O2 between 42.5 and 100.7 Torr. The main product was CF2BrC(O)F (yields 81-95% based on the CF2CFBr consumed). Minor amounts of C(O)F2 and C(O)FBr and traces of bromotrifluoroethene epoxide were also formed. The reaction is a chain reaction with bromine atoms as chain carriers. Its basic steps are: the thermal generation of CF3O{radical dot} radical by abstraction of fluorine atom from CF3OF, chain initiation by addition of CF3O{radical dot} to the double bond of alkene, leading, in presence of O2, to the formation of bromine atom and chain propagation by the reaction of bromine atom with CF2CFBr, originating CF2BrCFBrO{radical dot} radical. The predominant fate of the latter is the bromine atom extrusion with C{single bond}C bond scission playing the minor role. The full mechanism is postulated.
