| | 1,3-Dibromopropane Usage And Synthesis |
| Chemical Properties | 1,3-Dibromopropane is a colourless to slightly yellow liquid with sweet odor. soluble in ether, acetone and chloroform, insoluble in water. Decomposes when exposed to heat for a long time and is partially converted to 1,2-dibromopropane. Boiling with water produces propylene glycol. It is used substrate specificity of haloalkane dehalogenases. | | Uses | 1,3-Dibromopropane is used to prepare C3-bridged compounds through C-N coupling reactions. It is used in the preparation of 2,3,4,5-tetrahydro-7,7-diphenylimidazo- [2,1-b]-thiazine-6(7H)-one by reacting with potassium salt of 5,5-diphenyl-2-thiohydantoin. | | General Description | 1,3-Dibromopropane is a dihalogenated propane. It undergoes reduction catalyzed by electrogenerated solution-phase nickel(I) salen and nickel(I) salen confined in a polymer film on the surface of a carbon electrode to afford cyclopropane and propylene, respectively. | | Hazard | Colorless liquid; sweet odor. Insoluble in water;
soluble in organic solvents. Combustible. | | Synthesis | 1,3-Dibromopropane can be prepared via the free radical addition between allyl bromide and hydrogen bromide. It can derived from the reaction of propylene glycol with brominated hydrochloric acid. | | Purification Methods | 1,3-Dibromopropane [109-64-8] M 201.9, f -34.4o, b 63 -63.5o/26mm, 76 -77o/40mm, 9 0o/80mm, 165o/atm, d 4 1.977, n 1.522. Wash the dibromide with dilute aqueous Na2CO3, then water. Dry and fractionally distil it under reduced pressure. [Beilstein 1 IV 216.] |
