General Description

2-BROMO-1,1,1,3,3,4,4,5,5,5-DECAFLUORO-2-(TRIFLUOROMETHYL)PENTANE is a colorless fluorinated organic compound with the molecular formula C7H2BrF13. It is commonly used as a solvent in various industrial processes and is known for its low toxicity and high stability. This chemical is also utilized in the production of fluorinated polymers and as a refrigerant due to its low boiling point and thermal stability. Additionally, it is used as a starting material in the synthesis of various pharmaceuticals and agrochemicals. However, it is essential to handle and store 2-BROMO-1,1,1,3,3,4,4,5,5,5-DECAFLUORO-2-(TRIFLUOROMETHYL)PENTANE with care, as it can be harmful if ingested or inhaled and can cause irritation to the skin and eyes.

REACTIONS OF TERTIARY PERFLUOROALKYL HALIDES WITH HALIDE ANIONS

The reactivities of the F-tert.-alkyl halides (CF3CF2CF2(CF3)2CX (1a-c: X = I, Br Cl)) towards the corresponding lithium halides LiY (2a-c: Y = I, Br, Cl), in acetonitrile, reflect the electron acceptor properties of compounds 1 and the donator strength of the anions Y(1-).The tertiary carbanion F-2-methylpentanide acts as the key intermediate in the formation of the main products (F-2-methyl-2-pentene, F-2-methyl-1-pentene and F-2-hydro-2-methylpentane), and also of the halide substitution products obtained from 1a.No support for the participation of any perfluoroalkyl radical could be found.

Stable Perfluoroalkyl Carbanion Salts

The synthesis and properties of tris(dimethylamino)sulfonium (TAS) salts of perfluoro tertiary carbanions are desribed.Many of these unique salts are isolable and stable up to their melting points, and they dissolve in organic solvents to provide high concentrations of perfluoro carbanions.Several reactions of TAS+CF3CF2CF2C-(CF3)2, which exemplify the synthetic utility of these new salts, are reported.
