Polystyrene supported Dichloro-(8-aminoquinoline)-Palladium(II) complex catalyzed C H bond activation for ortho-acylation of 2-aryl pyridines

Polystyrene-supported Dichloro-(8-aminoquinoline)-Pd(II) complex C was synthesized and its catalytic efficiency was evaluated for ortho-acylation of 2-aryl pyridines with alcohols to form aryl ketones via cross dehydrogenative coupling. In addition in the presence of Pd(II) complex, toluene derivati...

description Polystyrene-supported Dichloro-(8-aminoquinoline)-Pd(II) complex C was synthesized and its catalytic efficiency was evaluated for ortho-acylation of 2-aryl pyridines with alcohols to form aryl ketones via cross dehydrogenative coupling. In addition in the presence of Pd(II) complex, toluene derivatives were also employed as an effective coupling partner for synthesis of aromatic ketones. Furthermore, this catalyst was highly stable and could be easily recovered by simple filtration and reused for four cycles with no significant decrease in its activity and selectivity.
