Abstract
Silver triflate is used as efficient catalyst for the intermolecular addition of 4-toluenesulfonamide to alkenes under thermal or microwave heating. The hydroamination of 1,3-dienes can be performed at 85 ˚C with low catalyst loading (0.1-5 mol%) or at room temperature using 1 mol% of AgOTf, the use of HOTf affording similar results.
Key words
alkenes - conjugated dienes - hydroamination - sulfonamides - silver catalysts
