Abstract
AbstractThe conformational analysis of a chiral acyclic ketone with one asymmetric carbon, (±)‐2,2,6,6‐tetramethyl‐5‐phenylheptan‐3‐one, has been achieved for the first time by means of an x‐ray diffraction study and the analysis of 1H1H and 13C1H geminal and vicinal coupling constants and 13C1H direct coupling constants. The application of the Durette‐Horton, Pachler and Altona empirical equations supports the hypothesis of a marked predominance in solution of the conformation observed in the solid state.
