Descripción

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.
