General description

Borane dimethyl sulfide complex (BMS) is a commonly used reagent and a mediator for hydroboration reaction for the preparation of organoborane compounds, which are utilized as key intermediates in organic synthesis. BMS is also employed as a reducing agent for the reduction of various functional groups such as aldehydes, ketones, epoxides, esters, and carboxylic acids to corresponding alcohols.

Application

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.

Packaging

The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
