Borane Dimethylsulfide


Other Names:

Borane-dimethyl sulfide complex

Dimethyl sulfide borane

(Dimethyl sulfide)trihydroboron

BMS




General Information:


Structure:



CAS Number: 13292-87-0

Molecular Weight: 75.96 g/mol

Appearance: Colorless liquid

Melting Point: -38 C

Density: 0.801 g/mL at 25 C


Borane dimethylsulfide (BMS) is a complex of borane with dimethylsulfide. The other common complex of borane is borane-THF. BMS is more stable than borane-THF and is therefore available in higher concentrations. BMS has the drawback of being smelly due to its dimethylsulfide content.




Common Uses:


Reagent for the reduction of carboxylic acids to alcohols





Reagent for the reduction of esters to alcohols





Reagent for the reduction of nitriles to amines





Safety:


Borane dimethylsulfide (BMS) is a flammable liquid.
