AMINOPHOSPHINES DERIVED FROM 1-AMINO-4-METHYLPIPERAZINE: SYNTHESIS, OXIDATION AND COMPLEXATION REACTIONS

Functionalized mono(amino)phosphines of the type Ph2PNHR (1) and bis (amino) phosphine of the type PhP(NHR)(2) (2) have been synthesized by treating Ph2PCl or PhPCl2 with 1-amino-4-methylpiperazine. Ligands react with aqueous hydrogen peroxide, elemental sulfur, or selenium to give the corresponding chalcogenides in good yields. The molybdenum complexes of the aminophosphines have been obtained. All of the new compounds were characterized by IR, H-1, and P-31-NMR spectroscopy and elemental analysis.
