Abstract

On the basis of coupling constants and chemical shifts the conformation of meso and racemic 2,3,4‐trichloropentanes have been determined. The meso isomer exists as an equilibrium between the expected rotameric forms but the racemic isomer is anomalous and exists almost entirely as a distorted form of a rotamer which has parallel 1:3 interactions. The significance of these conformations is discussed in relation to the likely conformation and stability of the corresponding stereoregular polymers, which may be derived from cis‐ and trans‐1, 2‐dichloroethylene.
