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.
