Abstract: N,N',N ''-Tricyclohexylguanidine was encapsulated in hydrophobic zeolite Y by reacting N,N'-dicyclohexylcarbodiimide with cyclohexylamine within the supercage. The encapsulated guanidine catalyzes the addition reaction of acetone to benzaldehyde forming 4-phenyl-4-hydroxybutan-2-one as the principal product, as opposed to the homogeneous system which produces 4-phenyl-3-buten-2-one via condensation reaction.
