%X Zirconocene olefin complexes
Cp2Zr(PPh2Me)(η2-RCHCH2) (R = H, Et, Ph) react rapidly
with 2
equiv of
[HB(C6F5)2]n
to give the zwitterionic products
Cp2Zr{η3-[CH(R)CH2BH(C6F5)2]}
(R = H (2a), Et (2b),
Ph (2c)) and the borane−phosphine adduct
Ph2MeP·
HB(C6F5)2.
Spectroscopic and structural evidence confirms an interaction between zirconium and the β-carbon
attached to boron, resulting in pentacoordinated carbon.
