Abstract
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.
