The initial assignments by Mahler and Pettit of relative configurations of the two racemic diastereomeric tricarbonyl‐( trans , trans ‐3,5‐heptadien‐2‐ol)iron complexes and to the two racemic diastereomeric tricarbonyl‐( trans ‐3,5‐hexadien‐2‐ol)iron complexes are consistent with NMR coupling constants, conformational analysis, previously reported Eu(fod) 3 lanthanide‐induced shift data and new Yb(dpm) 3 lanthanide‐induced shift data. A detailed discussion shows that, contrary to the claim by Foreman, the lanthanide‐induced shift data alone provide no new information regarding the relative configurations of these alcohols.
