2,2-dibromopropane is used in organic synthesis. dimethyl isopropenylsuccinate was formed as a by-product in the reaction of 2,2-dibromopropane. | [Preparation]
2,2-Dibromopropane synthesis: Ethyl bicyclic phosphite (3.5g, 0.025mole) and acetone (1.5g, 1. 9ml, 0.025mole) were dissolved in thirty ml benzene in a one-neck 100ml 19/22 standard taper flask and the solution was cooled to 5° by an ice bath. The solution was stirred by a magnetic stirrer and bar, and to it was added bromine (4g, 0.025mole) dropwise from a dropping funnel. The reaction proceeded immediately as no dibromide intermediate appeared, and after completion of halogen addition the solution was stirred for half an hour in the cold, and then analyzed for dihaloalkane . Analysis on the Beckman GC-2A Gas Chr omatograph indicated the presence of 2,2-Dibromopropane, and the yield was calculated as previously described. Yield: 1.56g, 31%.
2,2-dibromopropane is also prepared by Hydrogen bromide and propyne. |
