Abstract Because of the upsurge of interest inpolychlorobuta‐1,3‐diene derivatives as uncommoncontaminants in underground water, seven congeners, the threepentachloro‐ and four tetrachloro‐[( Z )‐ and( E )‐1,1,3,4‐tetrachloro‐,1,1,4,4‐tetrachloro‐ and( Z , Z )‐1,2,3,4‐tetrachloro]buta‐1,3‐dienes,were synthesized and their 1 H and 13 C NMRchemical shifts, n J ( 1 H, 1 H) and n J ( 13 C, 1 H) couplingconstants were measured. The 13 C NMR spectra were recordedin perdeuteroacetone with and without proton decoupling. In addition,to assign the 13 C NMR spectrum of1,1,2,4,4‐pentachlorobuta‐1,3‐diene, a2D‐INADEQUATE 13 C experiment was performed. Thepresent results were compared with literature data on organochlorinecompounds and possible conformations are discussed. © 1998 JohnWiley & Sons, Ltd.
