Abstract
A series of palladium (II) complexes bearing new amino-salicylaldimine ligands have been synthesized and structurally characterized. These palladium complexes showed the high catalytic activity for the Suzuki reaction of activated aryl chlorides with phenylboronic acid in DMF under air atmosphere A series of amino-salicylaldimine ligands, 5-R-3-morpholinomethyl-salicylaldimine (R = t-Bu, CH 3 , Br) have been synthesized and structurally analyzed. These tridentate ligands add to palladium (II) to give high yields of air-stable complexes that are characterized by IR, 1 H NMR and elemental analysis. Crystal structure details of complex 1 are presented. These Pd (II) complexes with amino-salicylaldimine ligands are versatile and efficient Suzuki catalysts towards cross-coupling of a variety of aryl chlorides with phenylboronic acid using DMF as solvent.
