Description

Application

Reagent used for the cis-vicinal diborylation of acetylenes and olefins with Pt catalysis; borylation of aromatics by Pd catalysis.

Substrate used in a new palladium-catalyzed cyclization of 1,6-enynes leading to homoallylic alkylboronates.

Used to construct a tetramethylpyrrolidine nitroxide scaffold for the synthesis of paramagnetic heterocycles by Suzuki coupling.

Boronic Acids - Aldrich ChemFiles 2007, 7.7, 3.

Most boronic acids readily undergo dehydration reactions to give a cyclic (trimer) anhydride. Our selection of boronic acids may contain varying amounts of this cyclic anhydride. Fortunately, the aci...
