One-Pot Synthesis of Aldol Adduct Catalyzed by Immobilized Picolylamine on Zirconia ()
ABSTRACT
Direct aldol reactions have been successfully performed using aromatic
aldehyde and cyclic ketone in nonpolar solvent by using immobilized
picolylamine on zirconia as a catalyst, in a double walled batch reactor. The
prepared catalyst was characterized by SEM, XRD and
FT-IR. FT-IR peaks reveal the presence of picolylamine on the surface of
zirconia. The catalyst shows excellent catalytic activity in aldol reaction of
cyclohexanone with benzaldehyde in cyclohexane giving 2-hydroxyphenylmethylcyclohexanone
(55.7% yield) in 4 hr at 80?C. Furthermore, the catalyst is recoverable by simple filtration and
could be used several times without significant loss in activity.
