Applicazioni

trans-beta-Styrylboronic acid as reagent is used for palladium (Pd)-catalyzed Suzuki-Miyaura coupling reactions, diastereoselective synthesis via Pd-catalyzed Heck-Suzuki cascade reaction and rhodium (Rh)-catalyzed intramolecular amination of aryl azides. It is also used as reagent in preparation of optically active unsaturated amino acids by diastereoselective Petasis borono-Mannich reaction and amino alcohol dienes via Petasis 3-component reaction using Ru-catalyzed ring-closing metathesis and isomerization.

Note

Stable under recommended storage conditions. Incompatible with oxidizing agents and heat.
