sulfonamides to alkenes and conjugated dienes can be carried out using a low loading of (triphenyl phosphite)gold(I) chloride and silver triflate as a catalytic mixture. The reaction can be performed under conventional thermal or microwave conditions and at rt in the case of dienes. Terminal alkenes undergo regioselective hydroamination at the internal carbon atom and dienes at the less substituted double bond
