Because of the upsurge of interest in polychlorobuta-1,3-diene derivatives as uncommon contaminants in underground water, seven congeners, the three pentachloro-and four tetrachloro-[(Z)-and (E)-1,1,3,4tetrachloro-, 1,1,4,4-tetrachloro-and (Z,Z)-1,2,3,4-tetrachloro]buta-1,3-dienes, were synthesized

โฆ Synopsis
H and lSC NMR chemical shifts are reported and assigned for 1,4,9,10-and 2,3,9,1 O-anthracenetetrone. In addition, NMR data are given for 2,3-dihydroxy-9, 1 O-anthraquinone, 2.3-dimethoxy-9.10anthraquinone and 1 -hydroxy-2-acetoxy-9,l O-anthraquinone, encountered during the preparation of the anthracenetetrones.

C and 15 N NMR data are reported for nine azoloazines. From the results obtained it is found that the 15 N chemical shifts are particularly well placed to provide reliable data on both the structures of the compounds studied and on their potential to undergo valence and prototropic tautomerism. Of p
The 13 C, 31 P and 1 H NMR spectra of a series of dioxaphosphinopyridines and pyridoazaphosphinines were studied. The interpretation of the chemical shifts of these compounds was based on model compounds and on selective irradiation and two-dimensional shift correlated NMR techniques.
