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.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Recommended storage temperature is 2 - 8°C. Store under inert gas. It is sensitive to moisture. Incompatible with oxidizing agents.

Homoallylic alcohols can also be formed by allylboration of aldehydes; the reaction has been found to be accelerated by Lewis acids, e.g. AlCl3 or Sc(OTf)3: J. Am. Chem. Soc., 124, 12414 (2002).
