摘要: Abstract A recyclable polymer–anchored Pd(II) complex C was synthesized and characterized using different spectroscopic techniques. In addition the catalytic efficiency of Pd (II) evaluated for ortho-acylation 2-aryl pyridines with toluene derivatives to form aryl ketones via cross dehydrogenative coupling. this process acts as an effective coupling partner upon sp3 H bond oxidation sp2 acylation in presence Pd(II)/TBHP system on water. Furthermore, catalyst highly stable could be easily recovered reused four cycles no significant decrease its activity selectivity.
