Ultrasound Mediated Hydroboration of Alkenes, Alkynes Employing: N,NDimethylaniline Borane (DMAB)
Author(s): Venkatesan Jayakumar, Mohammed Fakruddin Ali Ahamed
The current investigation highlights the efficiency of N,N-Dimethylaniline.borane (DMAB) as a hydroboration reagent towards various alkenes, alkynes, enyne and unsaturated ester under sonication condition, the organoboranes were formed in very good yields with short time. Besides these properties it displays excellent control of regiochemistry, chemo-selectivity compared to hydroboration experiments using THF.borane. The combination of borane species from amine.borane with ultrasound irradiation provides a convenient, rapid method for hydroboration of unsaturated molecules.
