Palladium-catalyzed hydroboration reaction of unactivated alkynes with bis (pinacolato) diboron in water?
RSC Advances Pub Date: 2022-03-29 DOI: 10.1039/D1RA09136K
Abstract
A highly efficient and mild palladium-catalyzed hydroboration of unactivated internal alkynes in water is described. Both aryl- and alkyl-substituted alkynes proceeded smoothly within the reaction time to afford the desired vinylboronates in moderate to high yields. Bis (pinacolato) diboron was used to afford α- and β-hydroborated products in the presence of HOAc. These reactions showed high reactivities and tolerance, thus providing a promising method for the synthesis of alkenyl boron compounds.
