摘要：

Ion-exchanged zeolites are efficient heterogeneous catalysts for the intramolecular addition of an amine H-NR2 to a CC triple bond. This was shown for the cyclisation of 6-aminohex-1-yne to 2-methyl-1,2-dehydropiperidine. For this reaction zinc(II)-exchanged zeolite BEA was one of the most active catalysts. The heterogeneous catalyst was more active than the corresponding homogeneous catalyst Zn(CF3SO3)(2), which is concluded to be related to co-catalysis between Lewis and Bronsted acid sites present in the zeolite.
