coordination of the OMe group to the zinc atom additionally takes place. All zinc complexes were investigated as catalysts in the intramolecular hydroamination of nonactivated alkynes and show high catalytic activity in the presence of the cocatalyst [PhNMe 2 H][SO 3 CF 3 ]. The zinc complex 1 shows the highest catalytic activity in most of the cyclization reactions. In this context, it was possible to isolate
