Article abstract of DOI:10.1021/om00026a046

Bis(carbomethoxy)palladium bipyridine is synthesized by the reaction of (bipy)PdCl₂ with LiOCH₃ under a CO atmosphere. NMR evidence for the apparent precursor to (bipy)Pd(CO₂CH₃)₂, i.e. (bipy)Pd(OCH₃)₂, was obtained in situ by NMR spectroscopy. (bipy)-Pd(CO₂CH₃)₂ crystallizes in the monoclinic space group C2/c with a = 16.851 (10) ?, b = 12.137 (5) ?, c = 7.088 (4) ?, β = 97.99(5)°, V = 1435(1) ?³, and Z = 4. The final refinement indices are R = 0.0681 and R(w) = 0.0774. The compound is thermally stable in methanol at temperatures up to 60°C; it decomposes in THF to yield methanol, bipyridine, and palladium metal.
