Borane dimethylsulfide
Chemical compound
Borane dimethylsulfide (BMS) is a chemical compound with the chemical formula BH3·S(CH3)2. It is an adduct between borane molecule (BH3) and dimethyl sulfide molecule (S(CH3)2). It is a complexed borane reagent that is used for hydroborations and reductions. The advantages of BMS over other borane reagents, such as borane-tetrahydrofuran, are its increased stability and higher solubility.[1] BMS is commercially available at much higher concentrations than its tetrahydrofuran counterpart (10 M) and does not require sodium borohydride as a stabilizer, which could result in undesired side reactions.[2] In contrast, BH3·THF requires sodium borohydride to inhibit reduction of THF to tributyl borate (B(OCH2CH2CH2CH3)3).[2] BMS is soluble in most aprotic solvents.
