摘要：

We found that 2-chloropyridine selectively precipitates Pd(II) over Pt(IV) in a HCl solution. The Pd(II) precipitated with a [ligand]/[Pd(II)] ratio of 1.9. Comparison of the Fourier transform infrared spectra of 2-chloropyridine and its Pd complex suggests that the ligand coordinated to the metal via the nitrogen atom on the pyridine ring.
