D. Rottger et al., HYDRIDE ABSTRACTION FROM (ETA(2)-ACETALDEHYDE)ZIRCONOCENE DIMER USINGB(C6F5)(3), Journal of organometallic chemistry, 508(1-2), 1996, pp. 263-265
B(C6F5)(3) reacts with the (eta(2)-acetaldehyde)zirconocene dimer (4)
by hydride transfer from the methyl group of a CH3CHO ligand to boron.
One of the metallaoxirane moieties of the dizirconium complex is then
opened to give the salt [(eta(2)-CH3CHO)ZrCp(2) .(H2C=CHO)ZrCp(2)](+)
[HB(C6F5)(3)](-)(6) that was isolated with an 80% yield.
