All three have been synthesized by various routes: 1-Bromo-2-chlorobenzene: from 2-chloroaniline, via diazotization followed by a Sandmeyer reaction [1]; 1-Bromo-3-chlorobenzene: by (3-chlorophenyl)trimethylgermanium by electrophilic substitution [2] [better source needed]
As one of the simplest such molecules, it is often cited as the prototypical chiral compound. [2] However, since there is no synthetic route known to produce bromochlorofluoroiodomethane, the related simple chiral compound bromochlorofluoromethane is used instead when such a compound is required for research.
Bromoiodomethane is a halomethane with the formula BrCH 2 I. It is a colorless liquid, although older samples appear yellow. It is a colorless liquid, although older samples appear yellow. The compound has been investigated as a reagent for cyclopropanation by the Simmons-Smith reaction , but diiodomethane and chloroiodomethane are preferred.
Bromodichloromethane is a trihalomethane with formula C H Br Cl 2.It is a colorless, nonflammable liquid which will dissolve in water, or evaporate in air. [1] Most of the chemical is produced through the chlorine disinfection process, [1] and as a result it can occur in municipally-treated drinking water. [2]
H 2 C=CH 2 + HBr → H 3 C-CH 2 Br. Bromoethane is inexpensive and would rarely be prepared in the laboratory. A laboratory synthesis includes reacting ethanol with a mixture of hydrobromic and sulfuric acids. An alternate route involves refluxing ethanol with phosphorus and bromine; phosphorus tribromide is generated in situ. [4]
Chloroiodomethane is used in cyclopropanation (Simmon-Smith reaction), where it often replaces diiodomethane because of higher yields and selectivity. It is also used in Mannich reaction, aminomethylation, epoxidation, ring opening and addition to terminal alkenes.
Bromo(chloro)fluoro(iodo)silane is a complex inorganic compound of bromine, chlorine, fluorine, iodine, and silicon with the chemical formula SiIBrClF. [2]
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br.It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers.
