Usage

General Description

Butane, 4-bromo-1,2-dichloro-1,1,2-trifluoro- is a chemical compound commonly used as a refrigerant and a propellant. It is a halogenated hydrocarbon with the formula C4H8BrCl2F3 and is known for its high stability and low toxicity. This chemical is commonly used in the production of aerosol sprays, blowing agents, and refrigerants due to its low boiling point and high vapor pressure. It is also commonly used as a solvent in the extraction of essential oils and as a propellant in household and industrial products. However, it is important to handle this chemical with caution as it is a known environmental pollutant and can have harmful effects on human health if exposure is not controlled.

Rearrangement of 3-membered 1,1,2-trifluorobromonium and iodonium ions and comparison of trifluorochloronium to fluorocarbenium ions

(Chemical Equation Presented) Reactions of chlorine (Cl2) with 4-halo-1,1,2-trifluorobut-1-enes (1, 2, or 3) give open-ion intermediates A and E that are in equilibrium. The open-chloronium ions (E) rearrange to a five-membered-ring halonium ion during ionic chlorination of 3 when the number-4 halo-substituent is iodine. Three-membered-ring bromonium and iodonium ions from alkenes 1, 2, or 3 are rather symmetrical and similar in structure. Quantum chemical calculations show that five-membered-ring halonium ion intermediates are 11 to 27 kcal/mol more stable than the three-membered-ring halonium ions or the open-ions A and E. The five-membered-ring intermediates lead to rearranged products. Rearranged products increase as the number-4 halogen (Z) becomes more nucleophilic (Z: Cl Br I). Open chloronium ions from ionic chlorination of terminal fluorovinyl alkenes are compared to the open ions generated by protons to similar alkenes.
