| Hazard Information | Back Directory | [Reactivity Profile]
Dimethylboron bromide is a mild Lewis acid capable of selective cleavage of ethers and acetals; deoxygenation of sulfoxides.
| [Synthesis]
Dimethylboron bromide can be conveniently prepared by treating Tetramethylstannane with Boron Tribromide.
| [Precautions]
Dimethylboron bromide is a flammable liquid, moisture sensitive; typically stored and dispensed as a 1.5-2 M solution in dichloromethane or dichloroethane. Solutions of this sort are stable for a period of months if stored at -15 °C and properly protected from moisture.
