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