Description and Uses
Triisopropyl borate is used as reagent in Pd-catalyzed coupling reaction with aryl halides such as Suzuki reaction. It is used as a reagent for the preparation of the boronic acids and esters; as a Lewis acid catalyst and involved in the ortho-borylation of 1-substituted naphthalenes. Furthermore, it plays an important role as a catalyst for the production of resins, waxes, paints and varnishes.
