Applications
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.

Solubility
Miscible with diethyl ether, tetrahydrofuran, dichloromethane, chloroform, carbon tetrachloride, toluene, and benzene.

Notes
Moisture sensitive. Store in a cool place.
