The Uses of Allylboronic acid pinacol ester
Allylboronic acid pinacol ester can act as reagent used for Palladium-catalyzed Suzuki-Miyaura cross-coupling reactions and olefin metathesis; Intermolecular radical additions; Allylboration of aldehydes catalyzed by chiral spirobiindane diol (SPINOL) based phosphoric acids and Cobalt-catalyzed regioselective hydrovinylation of dienes with alkenes ; Nucleic acid-templated energy transfer leading to a photorelease reaction .
The Uses of Allylboronic acid pinacol ester
Allylboronic acid pinacol ester reacts with carboxylic acids, in the presence of tri-n-butyltin hydride, to give homoallylic alcohols in good yield. Homoallylic alcohols can also be formed by allylboration of aldehydes. It is a reagent used for palladium-catalyzed Suzuki-Miyaura cross-coupling reactions and olefin metathesis, intermolecular radical additions, allylboration of aldehydes catalyzed by chiral spirobiindane diol (SPINOL) based phosphoric acids, cobalt-catalyzed regioselective hydrovinylation of dienes with alkenes, nucleic acid-templated energy transfer leading to a photorelease reaction and stereoselective indium-catalyzed Hosomi-Sakurai reactions.
