The reversible interconversion of the two complexes 1a and 1b confirms the long predicted possibility of the isomerization of ferrole complexes. That this could be successfully demonstrated in the case of 1 may also be attributable to the fact that the complex component Fe(CO) 3 (N 2 Et 2 ) leads to an electron density equalization in the ferrole unit, which facilitates flipping of the butadienediyl ligand.
