Abstract EN

The synthesis of neutral Pd complex, [Cl2Pd(r)'-Ph2PCH2CH2OCH3)2] 2, was carried out starting from [Cl2 Pd(PPh3)2] 1 in the presence of excess Ph2PCH2CH2OCH3 as hybrid ether-phosphine ligand for the first time.

[Pd (r|2-Ph2PCH2CH2OCH3)2](BF4)2 4 has been prepared in high yield by reacting two equimolar amounts of Ph2PCH2CH2OCH3 direct with [Pd (NCMe)4] (BF4)2 3 instead of treating 2 with two equivalent amount of AgBF4 reagent.

4 has served as precursor to synthesize [Pd (r|'-Ph2PCH2CH2OCH3)2diamine] (BF4)2 5Lr5L5 by mixing it with different kinds of diamante in CH2C12 individually.

Five diamantes were served as an incoming co-ligands, the (ether)oxygen atom easily displaced by 1,2-diamine (L|-L4) to produce the corresponding complexes with high yield, while 1,4-diamine (L5) required more synthetic-time and revealed low yield compared with the others, which can be attributed to the unstable seven dopamine-palladium membered ring (5L5) formation.

The chemical behavior of the phosphine ligands in these complexes has been investigated by 31P {'H) NMR spectroscopy in all the reactions processes.
