The major advantages of the MOF catalysts lie in the fact that
they can be readily recovered after the reaction and reused due to
their stability and heterogeneous nature.

To verify the stability of the catalyst under the experimental
conditions, leaching experiment was performed by examining the
1H NMR of the supernatant of reaction mixture. No leaching of TPT
or NSA ligand was observed in the supernatant. To further confirm
that the catalysis is indeed heterogeneous, we filtered the reaction
mixture after 5 h, and continued to monitor the progress of the
reactions in the filtrate. No further catalytic reactions has been
observed in the filtrated solution.
We also investigated the recyclability of this new Cu(I)-MOF
using piperidine (1a), benzaldehyde (2a) and phenylacetylene (3a).
The results are summarized in Table 4. In fact, the MOF catalyst
could be easily recovered by centrifuging the reaction mixture
after the reaction. The PXRD pattern indicates the crystal
structures of Cu(I)-MOF maintained after the catalytic reactions
(Fig. 2).

After washing the recovered MOF with CH2Cl2 (5 mL) to remove
traces of the previous reaction mixture and drying it under
vacuumed at 50 8C for 2 h, the MOF catalyst can be directly used in

may be easily recovered and successfully reused for up to 5 cycles
without any significant loss in the catalytic activity.

In summary, we have developed a new Cu(I)-MOF that is a
highly efficient catalyst for the three-component synthesis of
propargylamines under solvent-free conditions. The correspond-
ing propargylamines were obtained in good to excellent yields,
especially when piperidine was used as the amine component.
Heterogeneity tests demonstrate the absence of leaching under the
examined experimental conditions. The MOF catalyst can be
readily recycled and reused without major loss of their activity
for up to five cycles. This heterogeneous catalyst based on the
