2-BROMO-1,3,2-BENZODIOXABOROLE Chemical Properties,Usage,Production

Uses

B-Bromocatecholborane is a mild Lewis acid capable of selective cleavage of ether, ester and carbamate protecting groups; catalyst for Diels-Alder reactions.

Preparation

B-Bromocatecholborane can be conveniently prepared by treating Catechol with Boron Tribromide. The reagent is isolated by distillation as a moisture-sensitive, low-melting solid.

storage

B-Bromocatecholborane is a flammable solid, moisture sensitive; may be conveniently stored and dispensed as a 0.2 M solution in dichloromethane. If properly protected from moisture, these solutions are stable for a period of months[1]. Use in a fume hood.

Purification Methods

Keep at 20o/15mm for some time and then fractionally distil. [Gerrard J Chem Soc 1529 1959, Beilstein 6 IV 5612.]
