New
examples of the rare class of rhodium(I) ferrocenyl Fischer
carbene complexes 1–8, [Rh(LL)Cl{C(XR)Fc}]
[LL = cod, (CO)2, (CO, PR3) (R = Ph, Cy or OPh),
and (CO, AsPh3); XR = OEt or NHnPr] were prepared, and the electronic effects of coligands and alkoxy
vs aminocarbene substituents were investigated by spectroscopic and
electrochemical methods. The molecular structures of complexes 1, 2, and 4–6 were confirmed by single-crystal X-ray diffraction. The use of the
complexes 1–8 as homogeneous catalysts
for the hydroformylation of 1-octene was demonstrated, and the influence
of the carbene substituents and coligands on the activity and regioselectivity
of the catalysts evaluated. Finally, the stability of the Rh–Ccarbene bond of complex 1 under hydroformylation
conditions was confirmed with 13C NMR experiments.
