Borane-methyl sulfide complex Chemical Properties,Usage,Production

Chemical Properties

clear colorless to light yellow solution

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.

Uses

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.

General Description

Borane dimethyl sulfide complex (BMS) acts as a highly efficient and selective reducing agent in the presence of catalytic sodium tetrahydroborate for α-hydroxy esters. Asymmetric borane reduction of a variety of prochiral ketones with BMS using spiroborate esters as catalyst has been reported.
