Heteropoly acids: a green and efficient heterogeneous Brønsted 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.

Highly efficient and environmentally benign intermolecular hydroamination of non-activated olefins with amides and benzyl carbamate catalyzed by silicotungstic acid (HSiW) are described.
