erated for subsequent reactions. The fact that Ni2+ essen-
tially remains unchanged, is evident from an analysis by
UV-DRS, which shows the presence of only Ni2+ before and
after the reaction.

Conclusions
A very highly efficient nickel-catalyzed three-component
coupling of aldehyde, alkyne and amine by C–H activation
has been achieved under solvent-free conditions. Whereas
previous protocols require an inert gas, the present method-
ology proceeds readily in the presence of atmospheric oxy-
gen. This procedure is also environmentally friendly as it
does not require any organic solvents. Excellent yields,
milder reaction conditions and a solvent-free protocol are
other notable advantages of this method. Besides, catalyst
recovery and reusability are also achieved by using this pro-
cedure. Detailed studies on the mechanism and applications
of the current Ni-catalyzed additions to carbonyl com-
pounds are underway.

Experimental Section
General Procedure for the Ni-Zeolite-Catalyzed Condensation of Al-
dehydes, Amines, and Alkynes: Aldehydes (1.0 mmol), amines
(1.2 mmol), and then alkynes (1.2 mmol) were successively added
to Ni-Y (20 mg). After stirring at 80 °C for the respective time,
the mixture was diluted with dichloromethane. After removing the
catalyst by filtration, followed by solvent evaporation, the resulting
crude product was finally purified by column chromatography (sil-
ica gel). The recovered catalyst was thoroughly washed with ethyl
acetate and used for the next run.
