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.
