SYNTHESIS, CHARACTERIZATION AND AB INITIO CALCULATIONS OF AMINOPHOSPHINE DERIVED FROM 4-BENZYLPIPERIDINE, ITS CHALCOGENIDE DERIVATIVES AND MOLYBDENUM(0) COMPLEX

Functionalized monoaminophosphine PPh2NC5H9CH2C6H5 has been synthesized by treating Ph2PCl with 4-benzylpiperidine. The ligand reacts with aqueous hydrogen peroxide, elemental sulfur or selenium to give the corresponding chalcogenides in good yield. The molybdenum complex of the aminophosphine has been obtained. All of the new compounds were obtained in good yields and were characterized by IR, NMR, elemental analysis. Theoretical calculations were carried out by using the Hartree-Fock and density functional methods with the 6-31G(d) basis set. [Supplementary materials are available for this article.
