Abstract

Syntheses for [(diphenylphosphinoyl)methyl-4,5-dihydrooxazole (2) and [(diarylphosphinoyl)methylbenzoxazoles [aryl = phenyl (3), tolyl (4), 2-trifluoromethylphenyl (5) and 3,5-bis(trifluoromethyl)phenyl (6) have been developed. Each ligand has been characterized by spectroscopic methods and single crystal X-ray diffraction analyses have been completed for 2, 3, 4 and 5. The coordination chemistry of the ligands with Nd(NO₃)₃ and Yb(NO₃)₃ has been examined and structure determinations for [Nd(2)₂(NO₃)₃(CH ₃OH), [Nd(2)₂(NO₃)₃, [Yb(3) ₂(NO₃)₃(H₂O)·0.5(CH ₃OH), [Nd(3)₂(NO₃)₃· 3(CHCl₃), [Nd(4)₂(NO₃)₃(H ₂O), [Yb(4)₂(NO₃)₃(H₂O) and [Yb(5)₂(NO₃)₃(H₂O)·0. 5(CH₃CN) are reported. Depending upon conditions, the ligands act as monodentate PO or bidentate, chelating PO,N donors.
