Jj. Brunet et al., THE REACTION OF[PPN][HFE(CO)(4)] WITH STYRENE IN THF - AN UNEXPECTED AND FACILE SYNTHESIS OF [PPN](2)[FE-2(CO)(8)], Journal of organometallic chemistry, 461(1-2), 1993, pp. 169-172
The reaction of [PPN][HFe(CO)(4)] (PPN = bis(triphenylphosphine)iminiu
m) with styrene in refluxing tetrahydrofuran leads to the formation of
[PPN](2)[Fe-2(CO)(8)] which can be easily isolated (85% yield). The r
eaction mechanism is discussed.
