Useful:

• Canonical SMILES: [B-][S+](C)C
• Uses: Borane-dimethyl sulfide complex is used for hydroborations and reductions. Used with a dendrimeric supported L-pyrrolidinol in the asymmetric reduction of indanones and tetralones. CBS-catalyzed asymmetric reduction of ferrocenyl-1,3-diketones to 1,3-diols. Highly enantioselective reduction of ketones catalyzed by C3-symmetric tripodal hydroxyamides. Borane-dimethyl sulfide (BH3 Me2S) can be used as a reagent: For the selective synthesis of 1,3,5-oxygenated compounds from dimethyl 3-oxoglutarate. For the conversion of ozonides to alcohols. In the CBS-catalyzed asymmetric reduction of ferrocenyl-1,3-diketones to 1,3-diols. For enantioselective reduction of ketones to chiral secondary alcohols in the presence of C3-symmetric tripodal hydroxyamide as a ligand. For the hydroboration reduction and other applications. With a dendrimeric supported L-pyrrolidinol in the asymmetric reduction of indanones and tetralones.
