Abstract
A series of hexasubstituted butadienes of type A was prepared representing (E,E)-1,2,3,4-tetrachloro-5-methoxy-1,3-pentadienes (7) substituted by different terminal residues R. 1H n.m.r. data of diastereotopic methylene protons served to determine the barriers of rotation around the central CC single bond of the butadienes A. The considerable dependence of this barrier (ΔGmath image = 12.8–21.1 ...
