Heteropoly acids: a green and efficient heterogeneous Bronsted acidic catalyst for the intermolecular hydroamination of olefins

Intermolecular hydroamination of non-activated olefins with amides and benzyl carbamate proceeds efficiently in the presence of environmentally benign silicotungstic acid (HSiW) catalyst under mild conditions in air to afford addition products in good to excellent yields.
