Applications
CATECHOLBORANE is used in the transition metal catalyzed hydroboration of alkenes.1,2,3
Catecholborane is used to prepare B-alkylcatecholboranes. It finds application for the preparation of amides and macrocyclic lactams from carboxylic acids. It is used as a stereoselective reducing agent to convert beta-hydroxy ketones to syn 1,3-diols. Further, it reacts with alkyne through hydroboration to form trans vinyl borane, which is a precursor to Suzuki reaction.
