Popis: Au–Pd based catalytic systems are a unique couple due to the carbophilic Lewis acidity of Au and the redox properties of Pd. To gain more insight into this bimetallic couple, a synthetic and mechanistic investigation was conducted. As key substrates, ynamides (N-alkynyl allyloxycarbamates and N-alkynyl ethyloxycarbamates) were used. Essential for the mechanistic part was the isolation of the organogold(I) intermediate to validate the proposed mechanism. In total, 18 polysubstituted oxazolones and 12 organogold(I) complexes were synthesized.
