CATECHOLBORANE Chemical Properties,Uses,Production

Chemical Properties

CATECHOLBORANE is clear colorless solution

Uses

CATECHOLBORANE is used in the transition metal catalyzed hydroboration of alkenes.1,2,3

Uses

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.

Purification Methods

It is a moisture-sensitive flammable liquid which is purified by distillation in a vacuum under a N2 atmosphere and stored under N2 at 0-4o. It liberates H2 when added to H2O or MeOH. A solution in THF, after 25hours at 25o, has residual hydride of 95% (under N2) and 80% (under air) [Brown & Gupta J Am Chem Soc 97 5249 1975].
