Preparation and catalytic evaluation of a palladium catalyst deposited over two-dimensional zeolite ITQ-2 modified with N-donor groups
Original language description
Two-dimensional zeolite ITQ-2 was reacted successively with (3-chloropropyl)triethoxysilane, 2-(N,N-diethylamino)ethylamine, and ammonia to give a support bearing the Si(CH2)3NHCH2CH2NEt2 groups at the surface. Subsequent treatment with palladium(II) acetate afforded an immobilized palladium catalyst 3, which was tested in the Heck coupling of n-butyl acrylate with bromobenzene to give n-butyl cinnamate (4). This (pre)catalyst, which acts as a source of active metal species for the reaction occurring inthe liquid phase, showed good activity in N,N-dimethylformamide and N,N-dimethylacetamide at 150 degC. Reaction tests with different bases revealed a pronounced effect of the base additive on the course of the catalyzed process in terms of both the activity (yield of the coupling product) and selectivity [amount of n-butyl 3, 3-diphenylacrylate (5) resulting from twofold arylation]. Among the hydrated bases, the best yields of 4 were obtained in reactions performed in the presence of CH
