- CAS Number:22094-18-4
- Molecular formula:C5H10Br2O2
- Molecular Weight:261.94
Yield:22094-18-4 60%
Reaction Conditions:
with bromine at 0 - 20; for 15 h;
Steps:
29 1,3-dibromo-2,2-dimethoxypropane (29.2)
To a stirring solutionof compound 29.1(157g, 2.7 mol) in CH30H (1.6 L) at 0°Cwas added Br2 (950 g, 5.9 moL) dropwise, and the reactionwas stirred with warming tort for 15 hr. The precipitate was collected by filtration and was washed with cold methanol to yield5 compound29.2 (450 g, 60%) as a white solid.
