Cascade Reactions via Gold-Catalyzed Ammoniumation1 With their exceptional carbophilic acidity, cationic gold(I) complexes are the catalysts of choice in the activation of unsaturated carbon-carbon bonds for nucleophilic addition. In this area, we have recently disclosed the efficiency of gold to promote the addition of secondary sulfonamides, as primary nucleophile, onto alkynes toward the preparation of … Lire la suite de Gold Catalysis
