摘要
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) angstrom, b = 12.137 (5) angstrom, c = 7.088 (4)angstrom, beta = 97.99 (5)-degrees, V = 1435 (1) angstrom3, 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-degrees-C; it decomposes in THF to yield methanol, bipyridine, and palladium metal.
