General Description

1,2-Dichloro-1,1,2-trifluoro-4-iodobutane, also known as Halotron 1301, is a chemical compound that is commonly used as a fire extinguishing agent. It is a colorless, odorless gas that is highly stable and non-corrosive. It is effective in extinguishing fires involving flammable liquids, electrical equipment, and a variety of plastics. 1,2-Dichloro-1,1,2-trifluoro-4-iodobutane works by interrupting the chemical chain reaction of a fire, reducing the concentration of oxygen, and removing heat from the fire. It is considered to be an environmentally friendly alternative to other fire extinguishing agents, as it has a low ozone depletion potential and a short atmospheric lifetime. Due to its effectiveness and safety profile, it is widely used in industrial and commercial settings.

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.
