Yj. Wu et al., STRUCTURAL AND NMR SPECTROSCOPIC CHARACTERIZATION OF FERROCENE-CONTAINING ETA(3)-ALLYLPALLADIUM COMPLEXES, Journal of organometallic chemistry, 519(1-2), 1996, pp. 237-242
The reaction of 1,3-diferrocenylbut-2-en-1-one 1 with Li2PdCl4 in meth
anol in the presence of NaOAc produced mu-chloro-bridged eta(3)-allylp
alladium complex 2 in high yield. Treatment of 2 with PPh(3) afforded
the monomeric triphenylphosphine derivative 3. The anti conformation o
f 3 was confirmed by 2D H-1 NMR spectroscopy and also by X-ray crystal
lography.
