Abstract
An efficient and reusable Cu-exchanged tungstophosphoric acid catalyst is demonstrated for the solvent free hydroarylation and hydroamination reactions of alkynes with numerous arene and amine derivatives, respectively. The catalyst exhibited exceptionally high activity and regioselectivity in both the reactions.
Graphical abstractAn efficient reusable Cu-exchanged tungstophosphoric acid catalyst is demonstrated for the solvent free hydroarylation and hydroamination reactions of alkynes with different arene and amine derivatives under similar reaction conditions. The catalyst exhibited exceptional activity and afforded the analogues product with high regioselectivity with good to excellent yields.Download full-size image
