Bromoform is widely used as a solvent for waxes, oils and greases. It is utilized for mineral ore separation in geological tests. It is used as an intermediate in chemical synthesis as well as a laboratory reagent. It is the ingredient of fire-resistant chemicals and fluid gauges. It acts as a sedative and as cough reducing agent.
For examples of the generation of dibromocarbene, using Potassium tert-butoxide, A13947, as base, see: Org. Synth. Coll., 6, 187 (1988); 7, 200 (1990). Alternatively, reactions can be carried out with aqueous OH- and a phase-transfer catalyst such as Benzyltriethylammonium chloride, A13268: Org. Synth. Coll., 8, 223 (1993), or using crown ether catalysis: Org. Synth., 75, 98 (1997).
