Abstract

In this report, I have described the synthesis of P-N ligands as ligand 1 [N,N'-(hexane-1,6-diyl)bis(P,P-diphenylphosphinoselenoic amide)] , ligand 2 [N,N'-(hexane-1,6-diyl)bis(P,P-diphenylphosphinothioic amide)], and ligand 3 [N,N'-(hexane-1,6-diyl)bis(P,P-diphenylphosphinic amide)]. The reaction between different amine and PPh2Cl in ratio of 1:2 in toluene solution in presence of Et3N (2 molar) at room temperature for 24 h followed by the addition of elemental S/Se and H2O2 and further keeping for stirring for 12 h afforded these products. All of these compounds are characterized by 1
